fix(i18n): preserve remaining Vietnamese localization (#7935)

* fix(i18n): preserve remaining Vietnamese localization

* chore(quality): rebaseline file-size cap for 9 dashboard components (i18n wiring)

Restoring the Vietnamese localization on 9 dashboard components (useTranslations
wiring + t()/tc() call-site swaps for previously hardcoded strings) grows each
file by a small, irreducible amount. Bumps the frozen file-size-baseline.json
caps to match, with a justification entry per the project's own ratchet policy.

* fix(i18n): wire weekday localization + add missing qwen CLI description

Two gaps left by this PR's own new contract tests, caught while
reconciling the branch against the release tip:

- CostOverviewTab.tsx added formatWeekdayLabel() but never called it;
  the Weekly Usage Pattern chart still showed raw English day
  abbreviations regardless of locale. Now maps weeklyPattern rows
  through it before handing them to WeeklyPatternCard.
- cliTools.toolDescriptions was missing an entry for "qwen" (a
  baseUrlSupport:"full" tool) in both en.json and vi.json, failing
  the PR's own cli-catalog-display-contract.test.ts.

Covered by the PR's existing tests/unit/dashboard-localization-contract.test.ts
and tests/unit/cli-catalog-display-contract.test.ts (both now pass).

* i18n(vi): backfill the 4 proxySubscription keys #7299 added to en.json

#7299 (proxy subscriptions) merged while this branch was rebasing, adding
settings.proxySubscriptionsTab and settings.proxySubscription.error.{LOCAL_CORE_ENDPOINT_INVALID,
NEEDS_CORE_NOT_CONFIGURED,NO_USABLE_NODES} to en.json. This PR's own
i18n-vi-completeness contract asserts full en↔vi key parity, so the merge of the
current release tip surfaced them as missing. Adds the Vietnamese translations,
keeping the SS/VMess/Trojan/VLESS/SOCKS5 technical terms verbatim.
