Car status dashboard: ROTA + POTA-to-validate + session-fallback rows

[patrickrb]

What

Implements the Pane-layout status dashboard from the FT8AF CarPlay/Android Auto design exploration (Claude Design project). Extends the existing Android Auto status screen with the design's activation dashboard, whose defining behavior is "activation rows drop out, session stats take the slot."

Beside the existing POTA line, the pane now shows:

• ROTA row — ROTA <trip> · N QSOs with X.X mi driven this activation, read from RotaTripManager.state.
• POTA validation secondary — N more to validate the activation → Activation validated (POTA's 10-QSO program rule; no existing constant, so POTA_ACTIVATION_TARGET = 10 is defined here).
• Band decodes secondary — N decodes last cycle.
• Session-fallback row — Session · N QSOs / Last logged JA1XYZ · 20m · 41 min, shown only when neither POTA nor ROTA is active.

How

Decision/format logic lives in pure, Android-free helpers in CarQsoStatus.kt (buildCarActivationRows, potaValidateSpec, buildCarSessionRow, formatMiles, minutesAgo, carDecodesSecondary), unit-tested directly. QsoStatusScreen stays thin — it maps the app singletons (PotaSessionManager, RotaTripManager, GeneralVariables, FT8TransmitSignal.mutableQsoCompletedAt) into those helpers.

Both render paths use the same builder: the PaneTemplate fallback (older hosts) and the map Surface overlay (modern hosts) — CarSurfaceState.potaText is generalized to activationLines so ROTA/session appear on real devices, not just old hosts. The shared buildCarQsoStatus is left untouched, so the existing status/slot/band logic and its tests are unaffected.

Notes / judgment calls

• POTA and ROTA are practically mutually exclusive (parked at a park vs. roving on roads), so the rare both-active pane could hit a 4-row host limit and drop the last row; the common single-activation and idle cases fit.
• "Session QSOs" uses the today/yesterday worked-callsign set (QSL_Callsign_list_today) — the only cheap in-memory count; "last logged" is best-effort from the last partner + completion timestamp. Both documented at the call site.

Testing

• CarDashboardTest.kt — 17 new tests, 0 failures; existing car tests (incl. the manifest-wiring Robolectric test) still green: ./gradlew testDebugUnitTest --tests 'radio.ks3ckc.ft8af.car.*'.
• Full assembleDebug passes (validates the 9 new string resources + manifest merge).
• ⚠️ Not driven on a real head unit: no device was tethered, and Android Auto needs a DHU/AAOS host. The debug inject receiver also has no ROTA path yet — a follow-up could add one so the ROTA row is screenshot-testable on an emulator.

Pull request overview

Adds a pane-layout “activation dashboard” to the Android Auto/Car status UI so that POTA/ROTA activation rows appear while activating and collapse into a session-summary row when idle, and mirrors those activation lines onto the map surface overlay.

Changes:

• Introduces pure helper functions for activation/session row selection and formatting (POTA “to validate”, ROTA miles, session “last logged”, decode-count secondary), plus unit tests.
• Updates QsoStatusScreen to build activation/session rows (POTA + ROTA + session fallback) and to render them both in the PaneTemplate path and the Surface overlay.
• Adds new string resources for the new dashboard rows.

Heads up: holding this PR rather than merging it right now.

It conflicts structurally with #729 (Restore Android Auto — Play-approved IOT shape), which is merging first. #729 deletes CarMapSurfaceRenderer.kt, CarSurfaceState.kt, CarMapProjection.kt, and CarPanelLayout.kt because the NAVIGATION-category map/surface variant was rejected by Play review. This PR extends that same surface overlay, so once #729 lands, this branch will both conflict and re-introduce the rejected surface path.

The Copilot review comment here (per-cycle decode count) has been verified and fixed on this branch regardless.

Next step (separate follow-up): rebase on the new dev and port only the net-new, host-agnostic features from here — the POTA "N more to validate" secondary, the session-fallback row, and the per-cycle decode count — onto #729's pane path, dropping the surface-overlay changes. Leaving this open as the reference for that work.

[patrickrb]

Superseded by #731, which implements the same dashboard design on the pane path that landed with #729 (this PR was built on the map/surface overlay #729 deleted). Closing in favor of #731; reopen if needed.
