feat: Edit Profile for project founders (mirrors angor-profile web app)

[Copilot]

Implements the "Edit" button in My Projects → project card. Opens a full edit profile page matching the tab structure and functionality of profile.angor.io.

Relay Service (Angor.Shared)

• FetchProfileMetadataAsync — async task-based wrapper for kind-0 profile lookup
• FetchAppSpecificDataAsync — fetches kind-30078 (NIP-78) events by d tag (client-side filtered)
• PublishAppSpecificDataAsync — publishes kind-30078 events with a given d tag

SDK Operations (Angor.Sdk)

• FetchProjectProfileData — resolves project → fetches kind-0 metadata + angor:project / angor:faq / angor:members / angor:media in parallel; exposes FaqItem / MediaItem shared types
• UpdateProjectProfile — resolves founder key via IProjectService, derives project Nostr private key from wallet seed, publishes kind-0 + kind-30078 events

Both operations are exposed through IProjectAppService / ProjectAppService.

App Layer (App)

• EditProfileViewModel — reactive VM injecting only IProjectAppService (no direct SDK-layer service access); [Reactive] fields follow camelCase-without-underscore convention
• EditProfileView.axaml — 6-tab UI: Profile | Project | FAQ | Members | Media | Relays
• EditProfileView.axaml.cs — tab switching, back navigation, bubbled remove-item button handling
• MyProjectsViewModel — OpenEditProfile() / CloseEditProfile() + SelectedEditProject reactive state
• MyProjectsView.axaml.cs — PART_EditButton now calls vm.OpenEditProfile(project), visibility subscription mirrors the manage-project pattern
• CompositionRoot — registers Func<MyProjectItemViewModel, EditProfileViewModel> factory

Data flow

EditProfileViewModel
  └─ IProjectAppService.FetchProjectProfileData(projectId)
       └─ FetchProjectProfileDataHandler
            ├─ IProjectService.GetAsync → resolves NostrPubKey
            └─ IRelayService.Fetch{Profile,AppSpecificData} × 5 (parallel)

EditProfileViewModel.SaveAsync()
  └─ IProjectAppService.UpdateProjectProfile(walletId, projectId, metadata, ...)
       └─ UpdateProjectProfileHandler
            ├─ ISeedwordsProvider → wallet seed
            ├─ IDerivationOperations.DeriveProjectNostrPrivateKeyAsync(founderKey)
            └─ IRelayService.CreateNostrProfileAsync + PublishAppSpecificDataAsync × 4

@copilot why do we publish to PublishAppSpecificDataAsync on each content are they not stored all in one event?

[Copilot]

Each content type is intentionally a separate kind-30078 (NIP-78 AppSpecificData) event, differentiated by its d tag (angor:project, angor:faq, angor:members, angor:media). This is NIP-33 "parameterized replaceable events" — each unique (pubkey, kind, d) triple identifies one replaceable event, so a founder can update just their FAQ without republishing the project description, members list, etc.

The angor-profile web app does exactly the same: saveProjectContent, saveFaqContent, saveMediaContent, and saveMembers are separate functions each publishing their own kind-30078 event with the appropriate d tag (see createEventsFromData in relay.service.ts which constructs one event per section and then publishes them all in parallel via Promise.all).
