test(mobile-app): pin one-tap session send and harden flaky test timeouts

[iscekic]

Changelog for users

• One tap on the session send button sends the current message exactly once, with the keyboard open or closed — this behavior is unchanged by this PR.
• Microphone behavior and the composer's existing send states are unchanged.

Changelog for maintainers

• The reported two-tap send did not reproduce on device; one tap sends exactly once, so the diff ships no product change.
• A new mounted suite pins the one-tap contract: the first press sends with the keyboard open and closed and across input focus changes.
• The suite also pins the guards: an empty draft leaves send disabled and never sends, and a second press while sending is ignored.
• The new suite presses the real send handler after asserting it is enabled, so the full JS submit path runs as a device tap would.
• markdown-renderer.test.ts sets a file-wide 30 s test timeout; importing react-native-marked exceeds the 5 s default under full parallelism.
• auth-context.test.tsx gets the same 30 s timeout, wall-clock settle budgets instead of iteration counts, and 60 s per-test timeouts for retry backoffs.
• Review hint: weigh the device repro evidence against the reported defect before merging; the timeout bumps fix pre-existing flakiness in those suites.

Owner request

Fix the mobile session send button that requires two taps.

Surface: mobile-app.
On the session page, the send button sits to the right of the microphone icon and the composer.
Expected: One tap sends the current message exactly once.
Actual: The user must tap the send button twice.

Reproduce this through the normal session composer before changing product code.
Find and fix the shared cause across affected session flows.
Prove the first tap sends with the keyboard open and with the keyboard closed.
Cover focus changes, empty input, and duplicate-send prevention with focused regression checks.
Preserve microphone behavior and existing send states.
Put local end-to-end (E2E) device proof in the pull request (PR) body.
Use temporary test support outside the product diff.
Do not commit fixtures, E2E-only code, or test-only runtime flags.
Do not leave follow-ups.
Let the workflow open and maintain the PR.
Finish only after current-head continuous integration (CI) is green and Kilobot recommends Merge.
