Make the app react to unconfirmed text

[tomasMizera]

Our app currently ignores unconfirmed/underlined text on Android devices (see these reports for example: https://merginmaps.slack.com/archives/C02DWECUEN8/p1769847621711129, #4285) until it is confirmed.

Some languages rely on the unconfirmed text to enter proper characters (Japanese, Korean, Indian,...). The underline indicates a "Composing" state (e.g., typing "Tokyo" phonetically to get "東京").

This is an example of how the underline text looks like:

The app currently waits until the text is confirmed (by hitting space, dot, enter, back button, choosing a suggestion and more) to perform an action (validate input, search, ...). This results in a weird and unnatural UX when the app does not react to the input. People expect to see the app make an action immediately.

Let's do the following:

• Make the app react to the unconfirmed text immediately (hint: explore TextInput's preeditText and displayText props). This applies to:
  • Various text inputs across the app -> search bars (project, features, layers search )
  • Text and number inputs within the feature form
  • Text inputs in other parts (sign in/up forms, close account, ...)
• In general, we need to implement the fix in the base input components and it should propagate to the entire app automagically

Acceptance criteria:

1. The app does not wait for text confirmation (space, enter, suggestion selection) to perform the desired action.
2. The fix works on Android and iOS, for multiple popular keyboards (at least Samsung, Apple, Google and Microsoft SwiftKey keyboard)
3. Number inputs responds immediately too (verify numbers, minus sign, decimal separator sign)
