feat(session-list): copy session ID from the long-press menu

[chphch]

Add a "Copy session ID" action to the session quick-actions menu (long-press a session row, or the web actions popover) that copies the Happy session ID to the clipboard and shows the existing confirmation toast. Today the only way to grab a session's ID is to open Session Info and tap the "Happy Session ID" row — this surfaces the same copy one long-press away, alongside the existing (dev-only) "Copy session metadata" actions. The internal Claude/Codex ids keep their dedicated copy rows on the Session Info screen.

Implemented as a small copySessionIdToClipboard helper mirroring the existing copySessionMetadataToClipboard, wired into useSessionQuickActions's actionItems so every consumer picks it up automatically (the long-press Modal.alert menu in SessionsList / ActiveSessionsGroupCompact, and SessionActionsPopover). It reuses the existing sessionInfo.happySessionIdCopied / sessionInfo.failedToCopySessionId strings and adds one new label key sessionInfo.copySessionId across all 10 locales.

Proof

Verified end-to-end on web via a standalone happy-server (PGlite) + Expo web, authenticated with the dev-token URL bypass and driven headlessly with Playwright: the session action menu renders the new Copy session ID item, tapping it writes session.id to the clipboard (asserted navigator.clipboard.readText() === session.id), and the "Happy Session ID copied to clipboard" confirmation appears. pnpm typecheck is clean.

Proof — Copy session ID works end-to-end

Captured locally via a standalone happy-server (PGlite) + Expo web, authenticated through the getDevWebQueryCredentials() dev-token URL bypass and driven headlessly with Playwright.

The session action menu renders the new Copy session ID item; tapping it writes session.id to the clipboard (assertion: navigator.clipboard.readText() === session.id ✅) and the "Happy Session ID copied to clipboard" confirmation appears.

The action flows through useSessionQuickActions's actionItems, so it appears in every consumer (the long-press Modal.alert menu in SessionsList / ActiveSessionsGroupCompact, and SessionActionsPopover) with no per-surface wiring. Web renders the action menu compactly via Modal.alert; on device it's the native action sheet. pnpm typecheck is clean.
