[backport cloud/1.42] feat: add frontend subscription success recovery

[benceruleanlu]

Backports #11286

Summary

• backport frontend subscription success recovery to cloud/1.42
• resolve the automated cherry-pick conflicts in PricingTable.test.ts, SubscriptionRequiredDialogContent.vue, and useSubscription.ts
• adapt the recovery flow to cloud/1.42's Firebase auth store APIs instead of the newer auth-store wiring on main
• include branch-health follow-ups needed to validate and publish this backport cleanly on cloud/1.42

Why

The automated backport failed because cloud/1.42 had drifted in both tests and subscription/auth plumbing. The runtime behavior is still applicable on this branch, but the manual backport required:

• mapping the new checkout recovery flow onto useFirebaseAuthActions / useFirebaseAuthStore
• exporting SubscriptionTier from tierPricing.ts so the new checkout tracker types match the branch API surface
• repairing branch-local validation drift in .oxlintrc.json and knip maintenance config so the branch can pass its own commit/push gates with the current toolchain

Review Notes

Please review the final three follow-up commits separately from the main feature backport:

• fix: export subscription tier type for cloud 1.42
• chore: remove unsupported oxlint vue rule on cloud 1.42
• chore: align cloud 1.42 knip maintenance config

Validation

• pnpm exec vitest run src/platform/cloud/subscription/composables/useSubscription.test.ts src/platform/cloud/subscription/components/PricingTable.test.ts src/platform/cloud/subscription/utils/subscriptionCheckoutUtil.test.ts src/platform/telemetry/providers/cloud/GtmTelemetryProvider.test.ts
• pnpm typecheck
• pnpm exec oxlint src/platform/cloud/subscription src/platform/telemetry src/composables/auth/useFirebaseAuthActions.ts --type-aware
• pnpm knip --cache

Too messy, not worth when we're moving to 1.43 soon
