chore: fix all Biome lint warnings and MedDetail intake bell icons (#265)

- Backend: refactor nested ternaries, remove unused imports/any types
- Frontend: fix exhaustive deps, a11y label associations, array index keys,
  empty CSS blocks, unused vars, type annotations
- MedDetail modal: fix intake schedule bell icons not rendering (use unified
  intake source with fallback), place bell inline after person name
- MedDetail modal: revert schedule rows from grid to flexbox layout

Closes #264
