Refine night-row labeling and drop notifications

Weekday rows are night-only, so the moon glyph alone marks the
after-hours shift; the verbose time-range label is kept only on
weekend rows where day and night shifts coexist. Channel shift-change
notifications now label the shift on every day for parity. Thread the
caller's user_id through the regular-drop path instead of re-reading it
off the employee record, and document the user-facing changes.

+**Clearer shift drops and an easier-to-read schedule.** Two small quality-of-life
+improvements:
+
+- **`/oncall drop` can now say which shift to let go.** If you hold more than one
+  shift on the same day — say a holiday day slot *and* that night's after-hours
+  shift, or a weekend day *and* night shift — dropping no longer guesses for you.
+  The bot lists what you hold and asks you to add `day`, `night`, or `holiday`
+  (for example `/oncall drop saturday night`), the same way picking one up
+  already works. Asking to drop a shift you don't actually hold is turned down
+  instead of quietly dropping the wrong one.
+- **Night shifts stand out on the two-week post.** Day and night rows now carry
+  their own icons — a sun for the daytime shift and a moon for the after-hours
+  (night) shift — so the on-call row is easy to spot at a glance. Weekend rows,
+  which have both a day and a night shift, still spell out the full time range.
