Previously the name field auto-derived from the first text part when
the operator left it blank. That's brittle once reminders carry
multiple parts of varying provenance, and confusing in lists where
"Reminder" or partial sentences crowd in.
Now: every reminder must carry a non-empty name, capped at 60 chars.
- Zod schema on createReminder/updateReminder: name moves from
`z.string().nullable().optional()` to
`z.string().trim().min(1, "Give the reminder a name").max(60)`.
Stale-URL legacy callers that omit it now get a clear server error.
- Wizard compose step: input has `required` + `aria-required`,
placeholder + label simplified ("(optional)" tag and the helper
paragraph removed), Continue blocks on empty.
- Edit-message form: same — required, aria-required, save blocked
on empty, the "leave blank and we'll auto-derive" hint dropped.
- Review-submit client: defensive fail-fast for stale-bookmark URLs
that arrive at step 5 without a name — bounces back with
"Give the reminder a name (back on the Message step)" instead of
letting the server reject.
The resolveReminderName helper stays put — duplicateReminderAction
and any future caller still benefit from the trim+clamp+fallback
chain. Helper unit tests unaffected (they test the resolver in
isolation, the policy-tightening lives at the schema layer above).
298 web tests still passing.
