fix(mobile): enlarge icon-only controls to a reliable tap target

[iscekic]

Changelog for users

• The Filter sessions, Rename organization, and Invite member icon controls now expose a tappable area at least 28dp on a side.
• The active-filter count badge on Filter sessions still appears when filters are applied.
• Pressing each control still opens the filter sheet, the rename sheet, or the invite screen as before.

Changelog for maintainers

• New shared IconButton renders icon-only controls in a 32×32pt box with 8pt hitSlop, giving a 48pt effective target over the 28dp accessibility minimum and the 44pt DESIGN.md minimum.
• SessionFilterButton, the organization hub rename pencil, and the members Invite member control now render through IconButton, with the icon centered in a 20pt inner box.
• Previously these controls sized their accessibility node to the bare icon (20pt, 16pt, 22pt), which the accessibility check flagged as too small to tap.
• Review apps/mobile/src/components/ui/icon-button.tsx first: confirm caller className merges after the default box and that any caller hitSlop override stays adequate.
• Tests pin the box and tap-target minimums through a shared helper, and mounted tests cover each migrated control.
• No schema, configuration, or translation changes.

Owner request

Explorer finding: a control is too small to tap reliably

The user-agent explorer found this while using the app like a user.
One finding per item; the explorer never edits product code.

Flow: accessibility
Found on revision: fd04ca1

Repro:

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

Observed: controls below 28dp on a side: agents: 1 small control(s): Filter sessions (52x52px) org-manage: 1 small control(s): Rename organization (42x42px) org-members: 1 small control(s): Invite member (57x57px) profile-org: 1 small control(s): Rename organization (42x42px)
Expected: every control is at least 28dp on a side

Evidence (from the device run):

Follow-ups (not changed here)

• not proved live: Agents tab: tap the sliders 'Filter sessions' control in the header -> the filter sheet opens; with a filter applied the control shows the count badge and tapping it re-opens the sheet. (no capture cited it)
• not proved live: Open the organization deep-link entry (/(app)/(tabs)/(3_profile)/organization/) -> its Rename organization control opens the same sheet (the profile-org and org-manage entries share the control). (no capture cited it)
• not proved live: Organization -> Members: tap the 'Invite member' icon in the header -> the invite-member sheet opens. (no capture cited it)

Open findings (not fixed here)

• not proved live: agents.png is no longer on the host that took it, so no publish can carry it
• not proved live: e1h.png is no longer on the host that took it, so no publish can carry it
• not proved live: e1m.png is no longer on the host that took it, so no publish can carry it
• not proved live: home-ar.png is no longer on the host that took it, so no publish can carry it

This description names a scenario the proof did not capture:

• not proved live: Agents tab: tap the sliders 'Filter sessions' control in the header -> the filter sheet opens; with a filter applied the control shows the count badge and tapping it re-opens the sheet. (no capture cited 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.
