Fix Firefox inline button spacing on FAQ and About pages

[Copilot]

In Firefox, inline text buttons on the FAQ, About, and Feed Submission pages had no visible space between surrounding text and the button label — e.g. "However, toadd a feed" instead of "However, to add a feed".

Root cause

The spacer used before line-start inline buttons was  — the HTML entity for U+0014 (ASCII DC4, a non-printing control character). Chromium happens to render it as whitespace; Firefox does not.

Fix

Replace all 10 instances of  with {' '} (a proper JSX space) across three files:

• src/app/screens/FAQ.tsx — 7 occurrences
• src/app/[locale]/about/components/AboutPage.tsx — 2 occurrences
• src/app/screens/FeedSubmission/index.tsx — 1 occurrence

- However, to
+ However, to{' '}
  <Button variant='text' className='line-start inline' ...>

The line-start class (which zeroes left padding to avoid double-spacing) continues to work correctly — the space is now provided by a real U+0020 character rather than a control character.
