Handle Google Calendar working locations

[3mdistal]

Summary

• Sync Google eventType=workingLocation events with native workingLocationProperties, render all-day working locations in a slim translated lane above ordinary all-day events, and keep them non-blocking for availability.
• Preserve continuous multi-day all-day spans while separating the two lanes, with deterministic clipping and row packing covered by pure layout tests.
• Add a focused Home / Office / Other editor in popover and pinned-panel surfaces. Recurring events default to This day only, with an explicit All days option that still targets the visible instance ID.
• Keep Google payloads coherent: labels live in workingLocationProperties; the forbidden generic location field is stripped defensively; office metadata is preserved only while the event remains an office location.
• Record the working-hours API spike outcome: Google Calendar v3 exposes working-location events, but its Settings/discovery surface has no structured working-hours resource. No working-hours settings UI or Find a Time changes are included.

Verification

• pnpm -C templates/calendar test — 38 files, 231 tests passed
• pnpm -C templates/calendar typecheck
• pnpm -C templates/calendar build
• pnpm guard:i18n-catalogs — 16 catalog directories passed
• pnpm exec oxfmt --check <18 modified TypeScript files>
• git diff origin/main --check
• Rebasing onto current origin/main completed cleanly; every local gate above passed again after the final rebase.

Browser and provider QA

• Verified the working-location lane appears above ordinary all-day events on desktop and at 390px without horizontal overflow.
• Verified a Tuesday-through-Thursday ordinary all-day event remains one continuous span.
• Verified French chip, popover, pinned-panel, and aria-label text (Accueil, Lieu de travail : Accueil) and restored the app to English afterward.
• Created one disposable Home working location, changed it to Office and then Other through the native editor, and received HTTP 200 for both updates.
• Confirmed both action payloads omitted generic location; Google read-back returned native officeLocation / customLocation properties with transparency: transparent.
• Confirmed the chip and pinned heading updated immediately after each save.
• Deleted all disposable events and confirmed zero QA matches remained. Alice's existing recurring Home series was not mutated.

Successful user story

A hybrid worker can scan where they are working separately from all-day commitments, open a focused translated editor, change a visible location from Home to Office or Other, see the chip and pinned detail update immediately, and read the same native non-blocking properties back from Google Calendar. Ordinary multi-day all-day events remain a single continuous span below the location lane.

Risks and follow-ups

• A live mutation of Alice's real recurring working-location series was intentionally not performed. Unit/action coverage proves visible-instance IDs and scope: single|all; the UI default was verified read-only on an existing recurring occurrence.
• Weekly per-day location settings and copy-to-all remain deferred until the app has a real event-backed reconciliation action. Google Calendar v3 does not expose working-hours settings as structured provider data.
• Find a Time remains behaviorally unchanged.
• Separate pre-existing follow-up: manually changing create-dialog date inputs can retain the prior date state. It was reproduced outside the working-location edit path and is not introduced by this diff.
