fix(settings): simplify open source license notices

[maria-rcks]

Stacked on #8962.

This simplifies the open source license page to use the normal settings width, a compact header search, and single-line notice rows with right-aligned metadata.

Verified in the real web client at 1280x800 and 1920x1080, with web typecheck, formatting, targeted lint, and diff checks; lint reports only the two pre-existing request-effect warnings from #8962.

Built with gpt-5.6-sol in the Codex harness through T3 Code.

Note

Simplify open source license notices with collapsible rows and toggleable search

• Replaces the license row expand/collapse with externally controlled Collapsible components, allowing only one row open at a time via openEntryKey state in OpenSourceLicensesPanel
• Adds LicenseHeaderAction with a toggleable search icon: autofocus on open, blur closes when empty, Escape clears and closes
• Adds LicenseCount showing filtered vs total counts in the header
• Moves the project source link from inside the expanded panel to a trailing icon button in the row header
• Uses thirdPartyLicenseEntryKey for stable list item keys
• Risk: LicenseNoticeRow signature changed to accept controlled open state and onOpenChange callback; any consumers outside OpenSourceLicensesPanel would need updating

Note

Low Risk
Settings UI-only changes with no auth, data, or API impact; the main behavioral change is single-row expansion instead of multiple open notices.

Overview
Reworks the open-source licenses settings page to match standard settings layout and a denser list UI.

The page now uses SettingsSection (“Third-party notices”) with a header action instead of a wide layout, page title, and always-visible search bar. Search is a compact control: count + search icon that expands into an InputGroup (autofocus, Escape clears and closes, blur closes when empty).

Each notice is a single-line row with truncated name, version, and right-aligned license/bundle metadata. Rows use shared Collapsible components; only one row can be open at a time via parent openEntryKey. The project source link is an icon button on the row header rather than inside the expanded panel. List keys use thirdPartyLicenseEntryKey from shared.

Error and loading states drop extra borders and use smaller typography to align with the simplified section.

Approvability

Verdict: Approved at be8e961

Macroscope's review found this PR approvable — This is an isolated settings UI refactor that preserves existing license loading and filtering while making search and notice expansion more compact. Its runtime impact is limited to local presentation and interaction behavior, with no API, data, security, or infrastructure implications.
