Accept null content in updatePersonalExcerpt/updateIntelExcerpt and store
null when the submitted excerpt is empty instead of an empty Lexical state,
skipping the max-length check for blank submissions.

Convert the dossier personal excerpt from a plain textarea to Lexical
rich text (matching the intel excerpt) with a 1000-character plain-text
limit, and replace the static read-only cards on the profile page with
inline DossierExcerptEditors: owners edit their personal excerpt,
profiles:intel_excerpt:update holders edit the intelligence record.
Changes are validated server-side (lexicalPlaintextLength) and emit
dossier:personal-excerpt-update / dossier:intel-excerpt-update events.
Replace hasRoles calls with hasPermission in all server actions and page
components. Update qualification checks (logistics, intelligence) to use
permission-based checks instead of role name matching. Update staff lookup
in tickets/staff.ts to query roles collection. Use enlistmentDate field
on profile page instead of createdAt.
- Add profile page at /profile/[username] showing user service record
- Update NavUser dropdown to link to Service Record instead of Upgrade to Pro
- Remove unused Billing menu item from user dropdown
