feat: replace authorized representative input with contact selection dialog

Replace the plain text input for authorized representative with an
interactive contact selection interface that provides better UX and
maintains data consistency.

Changes:
- Add ProjectRepresentativeDialog component using EntityGrid for contact selection (excludes "You" and "Unnamed" special entities)
- Replace text input with clickable field showing contact icon, name, and DID
- Implement conditional UI states: initial "Assign..." placeholder vs assigned representative display with unset button
- Refactor selectedRepresentative to computed property derived from agentDid (single source of truth, prevents sync issues)
- Inline representativeDisplayName for simplicity
- Support changing representative by clicking on assigned field
- Support unsetting representative via trash button

The new implementation ensures agentDid remains the authoritative state while selectedRepresentative is automatically computed, preventing the previously possible desync when agentDid was set directly (e.g., via the
"make original owner an authorized representative" button).
