fix: copy current session share URL

[AjTheSpidey]

Fixes #2313.

The Share Session button was grabbing the URL too early. If the panel opened while the session params were still being written, it could copy a link without sid, sfrom, or sto.

This makes it read the current address bar URL when you actually click Share Session. I also added tests for the copied URL and the success/error notifications.

Tested locally with the focused Jest test, prettier, app typecheck, and eslint. ESLint had no errors, only the existing warnings.

Deep Review

🟡 P2 -- recommended

• packages/app/src/SessionSidePanel.tsx:75 -- notifications.show runs after the await with no mounted check, so closing the drawer (e.g. via the esc hotkey at :99) while navigator.clipboard.writeText is pending fires a Copied link to clipboard toast on whatever view the user landed on; the prior synchronous CopyToClipboard path could not produce this stale notification.
  • Fix: Capture a mounted flag in a useRef reset by a useEffect cleanup and gate the notifications.show call on it before firing.

🔵 P3 nitpicks (6)

• packages/app/src/SessionSidePanel.tsx:65-83 -- The button stays visually enabled while the copy is in flight, so the ref-based dedup silently drops rapid double-clicks (or a click during a slow clipboard permission prompt) with no user feedback.
  • Fix: Mirror the ref with a useState(false) and pass loading or disabled to the Button so the in-flight state is visible.
  • _{maintainability, julik-frontend-races}
• packages/app/src/SessionSidePanel.tsx:71-76 -- The try { ... } catch { copied = false } wrapper is dead under copyTextToClipboard's current contract (the helper catches internally and always returns Promise<boolean>), and would silently swallow any future real exception.
  • Fix: Drop the try/catch, keep isSharingSessionRef.current = false in a finally, and let any future contract change surface as a real error.
  • _{maintainability}
• packages/app/src/SessionSidePanel.tsx:81 -- Success message 'Copied link to clipboard' is a one-off; the peer URL-share handler in DBRowTableRowButtons already uses 'Copied shareable link!' for the same intent.
  • Fix: Either reuse the existing peer string or co-locate a CLIPBOARD_SUCCESS_MESSAGE next to CLIPBOARD_ERROR_MESSAGE in utils/clipboard.ts and consume both from there.
  • _{maintainability}
• packages/app/src/__tests__/SessionSidePanel.test.tsx:32 -- copyTextToClipboard as jest.Mock discards the helper's Promise<boolean> signature, so mockResolvedValue / mockRejectedValueOnce are never structurally checked against the real return type.
  • Fix: Replace with const copyTextToClipboardMock = jest.mocked(copyTextToClipboard); to type-check mock returns against the real signature.
  • _{kieran-typescript}
• packages/app/src/__tests__/SessionSidePanel.test.tsx:34-35 -- notificationsShowSpy is installed once at module scope; jest.clearAllMocks() in afterEach wipes call history but leaves the spy in place across the suite, which is fragile if anything else in the test environment reinstalls notifications.show.
  • Fix: Move the jest.spyOn(notifications, 'show').mockImplementation(...) into beforeEach, or pair it with jest.restoreAllMocks() in afterEach.
  • _testing
• packages/app/src/__tests__/SessionSidePanel.test.tsx:40-57 -- traceSource={{} as any}, sessionSource={{} as any}, and ... as any on the session literal cast away the component's prop contract in the new test fixtures.
  • Fix: Replace each {} as any with a minimal satisfies TTraceSource / satisfies TSessionSource / satisfies Session stub of just the fields the rendered tree reads.

Reviewers (6): correctness, testing, maintainability, project-standards, kieran-typescript, julik-frontend-races.

Testing gaps:

• No test unmounts the panel while copyTextToClipboard is pending, so the stale-notification regression is not pinned.
• No test asserts the Share button's in-progress affordance (disabled / loading) during the async window, so any future addition or removal of visual feedback would silently change UX.
