feat: add number format config, resource cap, and modal scroll fix

- Add user-configurable number format (suffix/scientific/engineering)
  - Suffix: K/M/B/T through Dc (1e33), then letter-based a/b/c... indefinitely
  - Scientific: 1.23e15 style via toExponential
  - Engineering: exponent always a multiple of 3 (1.23E15)
  - Stored in ProfileSettings, fetched from profile API on load
  - Picker UI in EditProfileModal with live examples
- Cap all resource accumulation at 1e300 (RESOURCE_CAP constant)
  - Per-resource FULL badge with tooltip in ResourceBar
  - Amber notice strip when any resource is at cap
  - handleClick also respects the cap
- Make EditProfileModal scrollable with viewport margin
  - Flex column layout with sticky header, scrollable form body
  - Bio textarea preserved as resizable with min-height
- Fix ReferenceError: formatNumber not defined in BossPanel/AchievementPanel
  - Pass formatNumber as prop to BossCard and AchievementCard
  - Pass formatNumber as parameter to conditionDescription
