* fix: preserve album track order during ATProto sync (#587)

when syncing album list records to ATProto, the background sync was
always ordering tracks by created_at, overwriting any custom order
the user had set via the frontend reorder feature.

now the sync:
1. fetches the existing ATProto list record order (if any)
2. preserves that order for existing tracks
3. appends any new tracks at the end (sorted by created_at)

this prevents user-reordered albums from reverting on login.

* feat: add atprotofans support link mode

adds three support link modes for artist profiles:
- none: no support link displayed
- atprotofans: links to atprotofans.com/profile/{handle}
- custom: user-provided https:// URL (existing behavior)

backend:
- validate support_url accepts 'atprotofans' magic value
- reject non-https URLs for custom links
- add tests for all three modes

frontend:
- portal page: radio button selector for support link mode
- artist profile: compute actual URL from mode + handle

* fix: validate atprotofans eligibility before selection

checks user's PDS for com.atprotofans.profile/self record with
acceptingSupporters=true before allowing atprotofans selection.

- client-side check on portal load (no backend sprawl)
- shows "set up" link when not eligible
- shows "ready" when eligible
- disables option when ineligible

* fix: use ATProto SDK for proper handle/PDS resolution

- add @atproto/api SDK to frontend for proper ATProto operations
- fix portal atprotofans eligibility check to resolve DID to PDS first
- fix backend handles.py to use AsyncIdResolver instead of bsky.social
- fix frontend error.svelte to use SDK for handle resolution

the issue was hardcoded bsky.social URLs which don't work for users
on self-hosted PDS instances. now we properly resolve DIDs via
plc.directory and query the user's actual PDS.

* feat: move like and comment PDS writes to background tasks

Likes:
- Update like/unlike endpoints to use optimistic DB writes
- Schedule PDS record operations via docket background tasks
- Make atproto_like_uri nullable to support async PDS writes
- Update tests to verify background task scheduling

Comments:
- Update create/update/delete comment endpoints to use optimistic DB writes
- Schedule PDS record operations via docket background tasks
- Make atproto_comment_uri nullable to support async PDS writes
- Update tests to verify background task scheduling

This reduces API response times by moving slow PDS writes to the background
while keeping the UI responsive with immediate local database updates.

the default docket worker polls redis every 250ms (4x/sec), which
caused ~3.4M redis commands in 2 days and $6.73 in upstash costs.

changes:
- add check_interval_seconds and scheduling_resolution_seconds to DocketSettings
- default both to 5 seconds (20x reduction in polling frequency)
- update background.py Worker to use these settings
- update audd costs in export_costs.py ($3.91 -> $9.13 for current period)

expected redis cost reduction: ~95% for idle polling

adds sync_album_list task to sync album ATProto list records immediately
after track operations, rather than waiting for the user's next login.

changes:
- add sync_album_list task and schedule_album_list_sync to background_tasks.py
- refactor _register_tasks to use docket.register_collection() per Guidry's advice
- call sync on: track upload, track delete, track album change, record restore
- mock schedule_album_list_sync in affected tests

fixes the issue where albums created during track upload didn't get
ATProto list records until the user logged in again.
