Fix pipeline config crashes, settings UX, invite roles, seed expertise tags

- Fix critical crash when clicking Edit on INTAKE stage configs: normalize
  DB fileRequirements shape (type/required → acceptedMimeTypes/isRequired),
  add null guard in getActiveCategoriesFromMimeTypes
- Fix config summary display for all stage types to handle seed data key
  mismatches (votingEnabled→juryVotingEnabled, minAssignmentsPerJuror→
  minLoadPerJuror, deterministic.rules→rules, etc.)
- Add AWARD_MASTER role to invite page dropdown and user router validations
- Restructure settings sidebar: Tags and Webhooks as direct links instead
  of nested tabs, remove redundant Quick Links section
- Seed 38 expertise tags across 7 categories (Marine Science, Technology,
  Policy, Conservation, Business, Education, Engineering)
