The Monday rollover was chat_update-ing in place, which only refreshes
content without moving the message to the bottom. Now it chat_deletes
the old post and chat_postMessages a fresh one so the schedule lands
at the bottom every Monday, independent of in-week activity.
Also added info-level logging to the bump handler silent return paths
so skipped bumps are observable at runtime.
* Add Slack admin modals + App Home admin section
Replace the two most error-prone positional admin commands with Block Kit
modals (override and holiday-add) opened from a new App Home admin section,
while keeping the typed subcommands as a fallback. Validation and side
effects are factored into shared helpers so the modal and command paths
can't drift, and every action/view handler re-checks is_admin against
get_admin_users() so a modal opened from Home can't bypass authorization.
Adds Schedule.list_overrides for the upcoming-overrides overview.
