Release 2.5.5.1: Bugfixes

This patch contains the following:

Bug Fixes

• Dead stream removal scoping — streams were incorrectly culled during targeted automation runs. Dead-state transitions are now gated to streams actually analyzed in the current pass via checked_stream_id_set. Unchecked streams retain their tracker state until a future full-check evaluates them.
• Automation cycle over-checking — all channels with checking enabled were full-checked every cycle regardless of activity. Channels now only enter the sync check queue when they received new stream assignments; channels with no assignments are skipped entirely.
• int/str type mismatch in channel dispatch — assigned_stream_ids keys were integers but the dispatch loop looked them up as strings, causing all channels to fall through to full-check. All channel ID lookups are now normalized to int.
• Profile save not persisting — SQLAlchemy's JSON column dirty-tracking silently skipped UPDATE statements when nested dict contents changed. Added flag_modified(p, "extra_settings") to update_profile to force the write.
• Frontend state mutation on toggle — updateProfile used a shallow copy of React state, causing nested objects like stream_checking to share references with the previous render. Replaced with JSON.parse(JSON.stringify(prev)) deep clone, ensuring toggles correctly isolate state changes.

Observability

• Added per-cycle dispatch summary log: N channels selected (X targeted, Y full-check, Z skipped) — visible at INFO level every automation run.
