fix(map): disable Save Map while pending and harden mobile save flows

## Summary

Harden the map save flow on three axes:

1. **Disable both Save Map triggers while a save mutation is pending** (sidebar + mobile floating overlay). Prevents the user from queuing duplicate saves or opening a second name dialog while one is in flight.
2. **Disable the settings-sheet Save Map button when no configuration changes are present** (bbox, zoom, or basemap still at defaults). Forces the settings flow to be config-first.
3. **Close the mobile settings sheet before opening the save-name dialog.** Keeps the modal stack tidy so the user is never hidden behind a sheet.

The mobile floating overlay intentionally has *no* `!hasConfigChanges` guard — it is a quick-action affordance that may save the current/default view at any time. Only the pending-disable applies. This asymmetry is now covered by a regression test so a future change to the floating button would fail the suite.

## Changes

- `src/screens/MapScreen/MapScreen.tsx`
  - `disabled={createMap.isPending || !hasConfigChanges}` on the settings-sheet Save Map button
  - `disabled={createMap.isPending}` on the mobile floating Save Map button (intentional, see comment)
  - `hasConfigChanges` useMemo: compares bbox / zoomRange / selectedStyle against defaults
  - `openNameDialog()` now closes the settings sheet before opening the name dialog
  - New i18n key `activeMapOnlineBadge` to distinguish online vs. offline active-map copy
- `src/i18n/messages/{en,es,pt}.json`: new `activeMapOnlineBadge` message in all three locales
- Tests: 9 new cases — both triggers disable while pending, both re-enable on settle, mobile default-state asymmetry, draw cancel, DownloadPanel integration, name-required error, no-project empty state, frame confirm happy path, map attribution

## Test coverage

MapScreen.tsx: 72.17% stmts / 68.83% branches → 94.78% stmts / 84.41% branches (all 4 metrics ≥ 80% per AGENTS.md)

Full suite: 2050 passed, 1 skipped (164 files)

## CI

All 15 required checks green. `mergeState: CLEAN`. Codex GPT-5.6-Sol independent readiness assessment: 5/5.
