feat(web): swipeable account rows, editable label, disabled-account guard

Accounts list (mobile):
* Each row is a SwipeableRow. Swipe right reveals Pair (or Unpair if
  the account is connected). Swipe left reveals Groups + Delete.
* The right shelf widens to 176px so two buttons fit comfortably; a
  new \`leftShelfWidth\`/\`rightShelfWidth\` prop on SwipeableRow drives
  the override (default 88 stays for single-button shelves).

Accounts list (desktop): unchanged grid of clickable cards.

Account detail:
* New "Name" card at the top opens /accounts/[id]/edit/label, the
  dedicated rename surface (mirrors the reminder edit-name pattern).
* Paired-at row now shows the full timestamp ("10 May 2026, 3:33:04 pm")
  via toLocaleString instead of toLocaleDateString.

Reminder wizard:
* Disconnected accounts on the "Account" step are no longer
  clickable. They render as a non-link with aria-disabled, dimmed
  to opacity-50 with cursor-not-allowed and a "Pair this account
  before scheduling a reminder from it" tooltip. The bot has no
  live session for those accounts, so this prevents broken submits.

renameAccountAction validates the label, rejects duplicates within
the same operator, and revalidates /accounts and the detail page.

Tests added:
* AccountSwipeableRow — 6 SSR tests (shelves rendered, conditional
  Pair/Unpair, Groups + Delete shelf, 176px shelf width, hidden
  accountId field).
* EditAccountLabelForm — 5 SSR + payload tests (prefill, Save
  button, required + maxLength=60, action call shape).
* StepAccount — 4 SSR tests (connected → Link, disconnected → no
  Link + aria-disabled, opacity/cursor styles, "Not connected"
  copy).

 # cm WhatsApp Reminder Bot
 
-Self-hosted WhatsApp reminder bot. Pairs multiple WhatsApp accounts via Telegram-delivered QR codes and sends scheduled reminders to groups.
+Self-hosted WhatsApp reminder bot. Pair multiple WhatsApp accounts via
+a browser-based PWA, schedule recurring reminders to groups, and watch
+the run history all from a phone home-screen icon.
 
 ## Status
 
-**Plan 1 complete.** Foundation, DB schema, and Telegram-driven WhatsApp pairing are working end-to-end. Reminder scheduling, the web dashboard, and production deploy are upcoming plans (`docs/superpowers/plans/`).
+**Plans 1, 2, and 3 complete.** The web app at `wabot.04080616.xyz` is
+the primary control surface; the Telegram bot has been removed.
 
 What's working today:
 
-- Single-operator Telegram bot with a whitelist + audit log of every command.
-- BotFather-style menu navigation: `/menu` opens a single message that edits in place as you navigate.
-- Pair a new WhatsApp account with `/menu` → 📡 Pair New → reply with a label. QR is delivered to Telegram and refreshed in place as it expires.
-- Browse paired accounts with 📒 Accounts. Tap an account → see groups, send a test text message, or unpair.
-- Group sync runs at pairing and on every Baileys `groups.upsert` / `groups.update` event, plus a manual 🔄 Refresh button. Removed groups are pruned automatically.
-- Auto-reconnect on transient drops; restart-survival via Baileys `useMultiFileAuthState` (no QR rescan needed across container restarts as long as WhatsApp hasn't logged the device out).
+- **Self-hosted Next.js 16 PWA** — installable on a phone home screen.
+  Mobile-first single-row header with a slide-out drawer; desktop
+  sidebar.
+- **Live QR pairing** — server-side Baileys session feeds the QR
+  payload directly into the browser via Server-Sent Events. Scan,
+  see "✅ Connected" within seconds, auto-redirect.
+- **Multi-account, multi-group reminders** — 5-step wizard
+  (Account → Message → When → Groups → Review) plus per-section edit
+  pages so you don't have to walk the wizard end-to-end to fix one
+  field. Active recurrence picker covers Daily / Weekly / Monthly /
+  Yearly with multi-rule support and per-rule fire-time pickers; the
+  rendered description reads as plain English ("Every week on Mon,
+  Wed, Fri at 09:00") not raw cron.
+- **Multi-message stacks** — a reminder can carry multiple ordered
+  parts (text + media), fired in sequence with a 1.5 s gap. Media
+  files swap at any time from the Edit Message page.
+- **Smart media handling** — per-kind WhatsApp size caps (5 MB image,
+  16 MB video/audio, 100 MB document). HEIC photos and `.mov` videos
+  fall back to the document delivery path so they reach the recipient
+  as a downloadable file instead of failing silently.
+- **Swipe-to-act rows** — on mobile, swipe a reminder or activity
+  row left for Delete or right for Pause/Restart/Archive. iOS-Mail
+  style.
+- **Activity tab** — last 200 runs with status filters (Success /
+  Partial / Failed / Skipped) plus an Archived tab. Archive a noisy
+  run to keep the main list readable; restore later. Hard-delete
+  always available. Run history survives a reminder deletion.
+- **Auto-reconnect on transient drops; restart-survival via Baileys
+  session persistence.** Pair once, the device stays linked across
+  container restarts.
+- **All actions audited.** Reminder run history queryable from the
+  UI; per-run target results (sent / failed / skipped) preserved
+  even when the underlying group is removed.
+
+Test count: **249 web + 31 shared + 26 bot = 306** passing.
 
 ## Host requirements
 
-Only Docker. No host Node, pnpm, or any other language toolchain — everything runs in containers via the long-lived `tools` service.
+Only Docker. No host Node, pnpm, or any other language toolchain —
+everything runs in containers via the long-lived `tools` sidecar.
 
 ## Architecture in one paragraph
 
-Two app containers and one external dependency. `bot` (Node.js) holds the live Baileys WhatsApp sessions, the grammy Telegram bot, and (in plan 2) a pg-boss scheduler. `web` (Next.js, plan 3) is stateless UI + API. `tools` is a long-running Node 22 + pnpm sidecar used for installs/tests/typechecks/migrations so the host doesn't need a Node toolchain. Postgres lives external at `192.168.0.210` in a `wabot` database. All cross-service communication goes through Postgres (`LISTEN/NOTIFY` for events, table writes for state).

-`docs/superpowers/plans/<next-date>-reminder-scheduling.md` — pg-boss, reminder CRUD via Telegram, fire-reminder handler, sender (text/image/video), retry policy, run history.
+- **Standalone media library** browser (currently media is uploaded
+  per-reminder).
+- **E2E browser tests** (Playwright) on the swipe and pairing flows.
+- **Auth** (passkeys / email-password) — bring back if URL exposure
+  becomes a concern. Today the app trusts whatever's in front of the
+  reverse proxy.
+- **Multi-operator** — schema supports `operator_id` on every row,
+  but the seed runs as a single operator and there's no /signup or
+  invite flow yet.
