### Motivation
- Subscription credit labels were rendering the refill date with
HTML-escaped separators (`/`) because `vue-i18n` parameter escaping
was applied to the date interpolation.
- The goal is to render date-only parameters like `MM/DD/YY` with
literal slashes so the UI shows a human-readable date string.
### Description
- Disabled `vue-i18n` parameter escaping for the
`subscription.creditsRemainingThisMonth` and
`subscription.creditsRemainingThisYear` lookups in both subscription
panels by passing `{ escapeParameter: false }` to `t()` in
`SubscriptionPanelContentLegacy.vue` and
`SubscriptionPanelContentWorkspace.vue`.
- Adjusted the unit test i18n setup in `SubscriptionPanel.test.ts` to
include `escapeParameter: true` in the test `i18n` instance and updated
the test messages to use `Included (Refills {date})`.
- Added a regression unit test in `SubscriptionPanel.test.ts` asserting
the rendered label contains `Included (Refills 12/31/24)` and does not
contain the escaped entity `/`.
### Testing
- Ran formatting with `pnpm format` which completed successfully.
- Ran lint via `pnpm lint` which passed with pre-existing warnings only
(no new errors).
- Ran type checking with `pnpm typecheck` (via `vue-tsc --noEmit`) which
completed successfully.
- Ran the modified unit tests with `pnpm vitest run
src/platform/cloud/subscription/components/SubscriptionPanel.test.ts`
and the test file passed (10 passed, 5 skipped).
- Attempted a Playwright-based visual capture of the running app but
Chromium crashed in this environment (SIGSEGV) before navigation, so no
screenshot was produced.

## Summary
Add frontend support for a Free subscription tier — login/signup page
restructuring, telemetry instrumentation, and tier-aware billing gating.
## Changes
- **What**:
- Restructure login/signup pages: OAuth buttons promoted as primary
sign-in method, email login available via progressive disclosure
- Add Free tier badge on Google sign-up button with dynamic credit count
from remote config
- Add `FREE` subscription tier to type system (tier pricing, tier rank,
registry types)
- Add `isFreeTier` computed to `useSubscription()`
- Disable credit top-up for Free tier users (dialogService,
purchaseCredits, popover CTA)
- Show subscription/upgrade dialog instead of top-up dialog when Free
tier user hits out-of-credits
- Add funnel telemetry: `trackLoginOpened`, enrich `trackSignupOpened`
with `free_tier_badge_shown`, track email toggle clicks
## Review Focus
- Tier gating logic: Free tier users should see "Upgrade" instead of
"Add Credits" and never reach the top-up flow
- Telemetry event design for Mixpanel funnel analysis
- Progressive disclosure UX on login/signup pages
