fix(accounts): sort Codex rows by plan remaining time

[HuiCheng]

Summary

The Codex accounts list shows paid plan remaining days but never sorts by them. sort=default is risk then filename. This PR adds sort=remaining and orders rows by the same subscriptionUntilMs the list already uses.

The branch starts at e19d8267 (upstream v1.12.12). HuiCheng main has diverged from that commit, and this environment cannot open a PR into seakee/CPA-Manager-Plus. The review base is cursor/v1.12.12-base-db8e so the diff stays the fix commits.

Scope

• Frontend panel
• Manager Server
• CPA panel mode
• Full Docker mode
• Native packages / release
• Docs / Wiki
• CI / build / tooling

Changes

• buildAccountRows stores subscriptionUntilMs from buildAccountSubscriptionPresentation.
• sortAccountRows honors sort=remaining with unknown or free plans last.
• The accounts sort dropdown exposes that key. Default sort is unchanged.

User Impact

On the accounts page, choose 套餐剩余时间 / Plan remaining. Ascending puts the soonest paid Codex expiry first.

Compatibility / Runtime Notes

• CPA panel mode: same frontend sort. No API change.
• Manager Server mode: same frontend sort. No API change.
• Full Docker / native packages: same after the panel rebuild.

Data / Security Notes

N/A. Sort uses existing local quota and token subscription fields.

Risk / Rollback

Risk level: Low

Rollback notes: revert the commits. Other sort keys are unchanged.

Verification

• Type check
• Lint (changed files)
• Tests
• Build
• Manual UI check (demo accounts in Chrome)
• Docs/link check
• Not applicable, docs-only

Default sort on the Codex demo list. Remaining days are 2, then 12, then 5.

Default sort does not order remaining days

After Plan remaining. Paid rows are 2 days, 5 days, 12 days, 23 days.

Plan remaining sort orders soonest expiry first
