[Performance] iOS - Keyboard sometimes takes seconds to appear when opening a chat: bump react-native-keyboard-controller and add instrumentation

[melvin-bot]

Problem

On native iOS, opening a report sometimes takes several seconds before the keyboard actually appears, and the page renders in a broken intermediate state while it waits. Reported as happening at least once a week.

Two things stand out:

• The keyboard should only open automatically when there is a message draft in the composer. In the reported case there was no draft, so the keyboard appearing at all may be a bug on top of the slowness.
• It has not been reproducible on a simulator or a physical device on production, and a codebase search found no path that should open the keyboard by default in a chat. So we need remote observability before we can chase it further.

Proposed work (can ship separately)

1. Bump react-native-keyboard-controller from 1.22.2 to 1.22.4. kirillzyusko/react-native-keyboard-controller#1598 looks potentially related.
2. Add Sentry instrumentation measuring how long the keyboard takes to open, so we can tell whether this is an isolated case or a broader problem and confirm whether the bump helps.

Notes

More detailed reproduction steps will be added if the issue happens again.
