feat(ui): dashboard-v2 views refactor (slice 3/3 of dashboard-v2) (#41503)

* feat(ui): add chat infrastructure modules (slice 1 of dashboard-v2)

New self-contained chat modules extracted from dashboard-v2-structure:

- chat/slash-commands.ts: slash command definitions and completions
- chat/slash-command-executor.ts: execute slash commands via gateway RPC
- chat/slash-command-executor.node.test.ts: test coverage
- chat/speech.ts: speech-to-text (STT) support
- chat/input-history.ts: per-session input history navigation
- chat/pinned-messages.ts: pinned message management
- chat/deleted-messages.ts: deleted message tracking
- chat/export.ts: shared exportChatMarkdown helper
- chat-export.ts: re-export shim for backwards compat

Gateway fix:
- Restore usage/cost stripping in chat.history sanitization
- Add test coverage for sanitization behavior

These modules are additive and tree-shaken — no existing code
imports them yet. They will be wired in subsequent slices.

* feat(ui): add utilities, theming, and i18n updates (slice 2 of dashboard-v2)

UI utilities and theming improvements extracted from dashboard-v2-structure:

Icons & formatting:
- icons.ts: expanded icon set for new dashboard views
- format.ts: date/number formatting helpers
- tool-labels.ts: human-readable tool name mappings

Theming:
- theme.ts: enhanced theme resolution and system theme support
- theme-transition.ts: simplified transition logic
- storage.ts: theme parsing improvements for settings persistence

Navigation & types:
- navigation.ts: extended tab definitions for dashboard-v2
- app-view-state.ts: expanded view state management
- types.ts: new type definitions (HealthSummary, ModelCatalogEntry, etc.)

Components:
- components/dashboard-header.ts: reusable header component

i18n:
- Updated en, pt-BR, zh-CN, zh-TW locales with new dashboard strings

All changes are additive or backwards-compatible. Build passes.
Part of #36853.
