feat(recurrence): Daily tab is "every day at <time>" — drop weekday choice

The Daily tab had two radios: "Every day" vs "Every weekday (Mon–Fri)".
That's confusing — Mon-Fri-only is a weekly pattern, not a daily one,
and it overlapped exactly with what the Weekly tab can already do
(select Mon, Tue, Wed, Thu, Fri).

So Daily now means literally every day. The tab body is just the time
picker plus a one-liner ("Fires once a day at the time below.").

Legacy reminders that stored "MM HH * * 1-5" still load fine — the
parser maps any DOW list (including the 1-5 range) onto a Weekly draft
with Mon-Fri pre-selected. So a saved "weekday" daily reminder shows
up as Weekly with the right days checked, no data loss.

RadioRow component went unused after this — removed.
