Add calendar app — shared events calendar with departments, staff tagging, bank holidays and two-way phone sync

Fastify/Postgres backend + React frontend matching the stack's app conventions, plus
a hand-rolled RFC 4791 CalDAV server (caldav-adapter turned out Koa-only in practice)
so calendars subscribe as genuine two-way sync in Apple/Google/Outlook. v1 scope:
multiple colour-coded calendars, department/staff event tagging via live Workforce
lookups, month/week/day/list views, dashboard, file attachments, activity log, and
an auto-synced UK bank holidays calendar. Verified end-to-end locally against real
Postgres: REST CRUD, CalDAV discovery/PROPFIND/REPORT/PUT/sync-collection, all-day
date handling, system-calendar write protection, and activity logging across both
the web and CalDAV write paths.
