The mobile `/water` worker experience (Tuxedo-only, matching the
existing water flow) now exposes a "Time" tab alongside "Headgates"
so irrigators can clock in/out from the same phone they use for
water entries — no second PIN.
- MobileWaterApp: new `activeTab` state, sticky TabBar rendered only
after PIN, screen='time' case embeds <TimeTrackingFieldClient>
with hardcoded Tuxedo brand constants.
- handlePinSubmit best-effort calls `verifyTimeTrackingPin` after
the water PIN succeeds, so the Time tab never re-prompts a worker
who is also set up in `time_tracking_workers`.
- handleLogout clears BOTH `wl_session` and `time_tracking_session`
cookies in independent try/catch blocks.
- Tab switching to Time drops in-flight water flow state; switching
back to Headgates restores the list without reload.
- i18n: added `tab.{headgates,time,logout}` strings (en + es); lifted
Tuxedo brand display constants into @/lib/water-log/brand so the
standalone /tuxedo/time-clock page and the embedded Time tab share
one source of truth.
