feat: recurring appointments with cascading change propagation (#28)

* feat: recurring appointments with cascading change propagation Implements GitHub issue #9 — recurring appointment scheduling with configurable frequency and cascade edit/cancel options. Changes: - DB: add `recurring_series` table (frequency_weeks) and series_id / series_index columns on appointments (migration 0003) - API POST /appointments: accepts optional `recurrence` object (frequencyWeeks + count) that creates a full series in one transaction - API PATCH /appointments/🆔 new `cascadeMode` field (this_only | this_and_future | all) applies time-delta shifts and field updates across the series - API DELETE /appointments/🆔 new `?cascade=` query param cancels this_only / this_and_future / all series members - Frontend: booking form gains a "Recurring appointment" checkbox with frequency and count pickers; calendar chips show a ↻ recurring label; detail modal shows "Recurring series" badge and a cascade-delete radio picker for series appointments Co-Authored-By: Paperclip <noreply@paperclip.ing> * fix: resolve TypeScript errors in recurring appointments route Guard against possibly-undefined results from Drizzle .returning() destructuring — use indexed access + explicit null checks instead of array destructuring for the recurring_series insert, and add an early throw when the series or first appointment row is missing.
