feat(desktop): restore archive identity UI in profile panel

[tellaho]

Category: new-feature
User Impact: Identity and agent profiles regain a Manage → Archive control, now guarded by a confirmation dialog that plainly explains what archiving does before it happens.

Problem: A prior holistic-pass merge stripped the archive-identity control out of the profile panel and deferred it. Beyond just restoring a button, the archive action needed to explain itself: archiving is relay-scoped and reversible, but without context it reads like account deletion — and the bot case (where permanent deletion lives elsewhere) was conflated with the human-identity case.

Solution: Restore the archive UI as a dedicated Manage section beneath the profile metadata, collapse the old six-prop drilling into a single useIdentityArchive hook, and gate the destructive-sounding action behind a calm, bot-aware confirmation dialog. The dialog reassures rather than alarms (secondary confirm button, not destructive red), splits its copy by identity type, and — for agents only — links to where permanent deletion actually lives (the Agents tab). The growing panel file was split along its natural seams to stay under the 1000-line cap.

File changes

desktop/src/features/identity-archive/hooks.ts
Introduces useIdentityArchive(pubkey), composing the three gate queries (relay membership, NIP-OA owner, archived status) plus current pubkey, owning both mutations and the toasted archive/unarchive callbacks. Returns { canArchive, isArchived, isPending, archive, unarchive }. Gate preserved verbatim: isSelf || isRelayAdminOrOwner || isOaOwnerOfViewee.

desktop/src/features/profile/ui/ArchiveConfirmDialog.tsx
New confirmation dialog gating the archive action. Bot-aware copy throughout ("Archive this agent?" vs "Archive this identity?"). Three effect bullets in a <ul> rendered as a sibling of AlertDialogDescription (which is a <p> and can't legally nest a list). Bot path adds a trailing paragraph linking to permanent deletion in the Agents tab; identity path renders no link (no delete target for a human). Confirm button styled secondary, not destructive.

desktop/src/features/profile/ui/ProfileManageSection.tsx
The Manage section hosting Archive/Unarchive. Lifts navigation here (useAppNavigation().goAgents()) and passes onGoToAgents into the dialog so the dialog stays presentational — the link closes the dialog first, then navigates (no routing behind an open modal). Unarchive stays a bare one-click recovery action.

desktop/src/features/profile/ui/ProfileFields.tsx
Extracted from the oversized panel file: field type, public/owner builders, the group + row layout, and the copy helper.

desktop/src/features/profile/ui/ProfileHero.tsx
Extracted hero header and collapsible description.

desktop/src/features/profile/ui/ProfileActions.tsx
Extracted primary actions, quick-action row, working badge, and ingress row.

desktop/src/features/profile/ui/profileSummaryTypes.ts
Shared profile/status types, broken out to avoid a circular import between the new sub-components.

desktop/src/features/profile/ui/UserProfilePanelSections.tsx
Reduced to ProfileSummaryView composition and focused views after the split. The Manage section now renders below the metadata field group. Pure refactor of render output — same gate, same section order, testids intact.

desktop/tests/e2e/identity-archive.spec.ts
Restores the 5-case e2e gate matrix dropped by the earlier UI removal, now testid-driven. Case 1 clicks through the confirmation dialog.

Reproduction steps

1. Run the desktop app and open a profile panel for an identity you can manage (self, or one where you're relay admin/owner, or NIP-OA owner of the viewee).
2. Scroll past the metadata fields (Channels → Public key → Agent type → Capabilities) to the new Manage section at the bottom.
3. Click Archive — confirm the dialog opens with a calm secondary button, a three-bullet effects list, and copy matching the identity type.
4. For an agent profile: verify the trailing paragraph links to the Agents tab; clicking it closes the dialog and navigates to /agents.
5. For a human identity: verify there is no link in the dialog.
6. Confirm archiving applies the "Archived on this relay" flair under the display name; Unarchive is a one-click recovery with no dialog.
