feat(me): inline profile editing in the Profile tab (P3b)

Wires existing updateMyProfile + discloseAffiliations into an editable
form (name, handle, phone, bio, skills, interests, willing-to,
affiliations). Affiliations re-disclosed only when changed so the COI
timestamp is not reset on every save. Added bio to the updateMyProfile
param type (schema + column already supported it). 521 tests; build
clean (UI not browser-tested from here).
