rebrand: Workavia Mail (tier 1+2+3+4)

Tier 1+2 - web/UI user-facing:
- Replace all visible "Twake Mail" / "Linagora" with "Workavia Mail"
- Swap 3 logo SVGs (icon kept, wordmark replaced via SVG <text>)
- Splash: replace icon_twp.png with HTML <div>Workavia</div>
- Remove power_by_linagora.svg, replace with AGPL SourceLinkWidget
- Patch web/index.html, manifest.json, login/logout-callback HTMLs
- Patch all 16 ARB locales + scribe ARB + app_localizations.dart
- Patch 4 web/i18n/*.json (FR/EN/DE/VI smart banner titles)
- App grid reduced to "Mail" + "Calendar"
- User-Agent: Twake-Mail -> Workavia-Mail

Tier 3+4 - mobile native:
- Bundle ID: com.linagora.{android,ios}.teammail -> com.workavia.mail
- URL schemes consolidated: teammail.mobile/twakemail.mobile -> workaviamail.mobile
- Android: applicationId, namespace, AndroidManifest, strings.xml
- Android: move Kotlin sources com.linagora.android.tmail -> com.workavia.mail
- Android: empty branding.xml + android12branding.xml (vector text not patchable)
- iOS: Info.plist (CFBundleDisplayName/Name, schemes), Runner.entitlements
- iOS: TwakeMailNSE + TeamMailShareExtension entitlements + Info.plist
- iOS: Runner.xcodeproj (12x PRODUCT_BUNDLE_IDENTIFIER, 9x APP_GROUP_ID)
- iOS: TokenRefreshManager.swift redirect URLs
- iOS: fastlane Appfile + Matchfile
- Dart: oidc_constant, app_config keychain, notification MethodChannel

Known follow-ups (require user action):
- Apple Team ID KUT463DS29 (still Linagora) -> needs Workavia team for App Store
- Android branding.xml emptied: need PNG/path-converted wordmark for splash
- iOS sub-bundle paths (TwakeMailNSE/, TeamMailShareExtension/) on disk unchanged
- iOS App Store URL emptied; Play Store ID points to com.workavia.mail
