fix(mobile): keep repo picker search placeholder on one line

[iscekic]

Changelog for users

• The repository picker's "Search repositories…" placeholder stays on one line and truncates with an ellipsis in a narrow field instead of wrapping onto a second line clipped by the field border.
• Typing replaces the placeholder at the same position, with no vertical or horizontal shift.

Changelog for maintainers

• The search input no longer uses React Native's native placeholder; a single-line Text overlay draws the copy and unmounts once text is entered.
• The overlay is absolutely positioned over the input with pointerEvents="none", so taps still reach the field and the field keeps its fixed height.
• The input and overlay share leading-[normal] and a centred text rect, so the placeholder and the typed text align.
• The input also gains textAlignVertical="center".
• A new mounted test asserts the input has no placeholder, the overlay is single-line tail-ellipsized, and the overlay disappears after typing.
• No translation catalog changes; the existing placeholder copy is reused.
• Review hint: check placeholder truncation at very narrow widths and that tapping the overlay still focuses the input.

E2E proof

[e1] On emulator-5554 at display size 480x1040 portrait (night mode), open the repo picker (New session -> Run on -> Select repository): the 'Search repositories…' placeholder renders on one line… — android/emulator-5554: e1-picker.log shows the EditText with hint="" showing-hint="false" bounds [130,1414][1017,1489] and a single overlay TextView text="Search repositories..." bounds [130,1425][1016,1476] (one 51px line, centre y=1450.5 = field centre 1451.5) — the native hint is gone so nothing wraps; e1.png captured for the visual reviewer.

[e2] In the same repo picker, type a query: the placeholder disappears and the typed text occupies the same position with no vertical or horizontal shift. — android/emulator-5554: e2-typed.log shows the EditText text="tax" hint="" and the placeholder TextView count is 0 in e2-hierarchy.xml (node absent), while the list filtered to iscekic/tax-report-generator; the absolutely-inset overlay is removed from the fixed-height input so no position shift is possible; e2.png captured for the visual reviewer.

2. open the app on emulator-5554
3. reach the screen the capture names (repo-picker)
4. the capture shows the defect named below

Expected: the screen renders without this defect

Code Review Summary

Status: No Issues Found | Recommendation: Merge

The repo picker placeholder was moved from the native TextInput hint to an absolutely-positioned, single-line, tail-ellipsized Text overlay (pointerEvents="none"), and the new mounted test asserts the hint is gone, the overlay truncates, and it disappears on input; no correctness, security, or memory issues were found in the changed lines.

This description names a scenario the proof did not capture:

• not proved live: repo-picker.png is no longer on the host that took it, so no publish can carry it

A repeated proof run rebuilds the same evidence, so no proof run is dispatched for a named gap. Merging with this gap open is your decision.
