fix(idaa/recovery_meetings): fix weekday chips, recurring fields, and timezone lookup

- Weekday chips: replace bind:checked (unreliable with dynamic bracket notation in
  {#each}) with explicit onchange handlers + class: directives; read weekdays from
  state in submit handler instead of FormData
- Recurring pattern/times: bind select and time inputs to working copy
  so values display and edit correctly
- Times clearing: map empty string to null so times can be cleared once set
- liveQuery guard: skip event_obj sync while edit form is open to prevent
  background refresh from overwriting in-progress user changes
- Timezone lookup: forward order_by_li, limit, offset through the full call chain
  so priority sort and result count params are actually sent to the API
