Makes the inline upgrade badge a tiny star + short label (Pro on gplay, FOSS on foss) instead of icon-only. Text is flavor-switched via upgrade_badge_label in each flavor's strings.xml, primary color, labelSmall typography, no pill background to keep it lightweight when multiple rows stack it. Accessibility uses the existing common_upgrade_required_label.
Add dedicated Compose upgrade screens for both FOSS and gplay flavors, presenting pro benefits before the purchase/sponsor action. Migrate all upgrade dialog callers to navigate to the new screen instead.
This commit introduces localized error messages for Google Play billing issues and refactors the error handling in `UpgradeRepoGplay`.
- `BillingException` and `BillingResultException` now implement `HasLocalizedError` to provide user-friendly error messages.
- New string translations for billing error labels and descriptions have been added for various languages.
- `UpgradeRepoGplay` now includes an `error` field in its `Info` state to propagate billing errors.
- The `upgradeInfo` flow in `UpgradeRepoGplay` has been updated with a `retryWhen` operator to handle errors more gracefully. If an error occurs but the pro state was recent, it emits a grace period state. Otherwise, it emits the error.
- `OverviewFragmentVM` now observes `upgradeState` and posts any non-pro errors to `errorEvents` for display.
