feat(recurrence): per-rule fire time on every tab; drop redundant labels

Each schedule row in the recurrence picker now owns its own HH:MM
fire time. Previously every row inherited the time from the date+time
inputs above, which meant you couldn't say "every Monday at 09:00 AND
every Friday at 17:00" — both rules shared whatever the form-level
time was.

The Daily / Weekly / Monthly / Yearly tabs each render a small
"Fires at" time field. The picker still seeds new rules with the
form's date+time so the most common case (one rule, time matches the
first fire) doesn't need extra clicks.

Round-trip: the cron line `35 17 * * 1` now restores hour=17, minute=35
on a weekly draft. The parser pulls MM HH off the front of every
expression and feeds the rest of the pattern matchers as before.

Also clean up two pieces of duplicated/obsolete UI feedback in both
the wizard When step and the edit When form:

  - Removed the `<p>` showing "Cron: 0 9 * * *" — the per-row
    description ("Every day at 09:00") already says it, in human form.
  - Removed the standalone "Times are in Asia/Kuala_Lumpur" footer.
    The timezone is shown elsewhere (header) and the cron output is
    always evaluated in the configured zone — telling the user "times
    are in <tz>" inline in the picker is noise.
