Dev: Fix useExhaustiveDependencies — Mobile ASA-Go

[conbrad]

Describe the task
Remove biome-ignore lint/correctness/useExhaustiveDependencies comments and properly fix dep arrays in the ASA-Go mobile app.

Acceptance Criteria

• Remove biome-ignore comments from mobile/asa-go/src/App.tsx (lines 109, 127)
• Remove biome-ignore comments from mobile/asa-go/src/components/map/ASAGoMap.tsx (lines 212, 221, 241, 257, 275)
• Remove biome-ignore comments from mobile/asa-go/src/components/map/ScaleContainer.tsx (line 10)
• Remove biome-ignore comments from mobile/asa-go/src/components/settings/Settings.tsx (line 48)
• Remove biome-ignore comments from mobile/asa-go/src/hooks/usePushNotifications.ts (line 115)
• Biome lint passes with zero `useExhaustiveDependencies` errors — run from repo root: `./web/node_modules/.bin/biome lint mobile/asa-go/src/`
• Map initializes, layers render, and scale updates correctly in the mobile app
• Network status changes correctly toggle basemap visibility
• Push notification registration works correctly

Additional context

• Must lint from the repo root (not from `web/`), as `biome.json` `includes` patterns are relative to the repo root.
• `ASAGoMap.tsx` has 5 affected effects — review carefully for OL layer lifecycle, similar to the shared Map components task.

Closing — biome lint confirms no useExhaustiveDependencies violations in mobile/asa-go.

Reopening — ASA-Go does have useExhaustiveDependencies violations when scanned from the repo root (biome.json includes patterns require that). biome-ignore comments have been added; this issue tracks properly fixing the dep arrays.
