fix(docs): remove aggressive word-break CSS that splits words mid-syllable (#21068)

## Summary
- Removes `word-break: break-all` from table cells which was breaking
words at arbitrary characters (e.g., "to-kens", "sequenc-er",
"del-egated")
- Removes `table-layout: fixed` and arbitrary `min-width`/`max-width`
column constraints that forced narrow columns
- Keeps `overflow-wrap: break-word` which only breaks words that are
genuinely too long (like hex addresses)

## Test plan
- [ ] Verify the governance "Quick Summary for Token Holders" table no
longer breaks words mid-syllable
- [ ] Check tables with long content (e.g., contract addresses) still
wrap correctly
- [ ] Verify no horizontal overflow on narrow viewports
