-*** Description
-
-Task logdata now uses generic, source-agnostic field names instead of
-per-source prefixed keys. `TaskLogData` gained `source_id`, `project_id`,
-`state` and `raw_data` (the full remaining source payload kept for future
-reference, matching the music track `raw_data` convention); the old `orgmode_*`
-and `todoist_*` keys are gone. The todoist and emacs scrobblers and webhooks
-normalize into the generic fields, and all `log__orgmode_id` / `log__todoist_id`
-lookups became `log__source_id`. `Task.source_url_for_user()` now reads
-`source_id` (fixing the `todist_id` typo and the never-matching log `source`
-check). New `convert_orgmode_task_log_to_generic` /
-`convert_todoist_task_log_to_generic` helpers (wired into the
-`convert_task_log_data` management command) migrate existing scrobble logs.
-The scrobble "Edit Log" form no longer renders the read-only fields (labels,
-source_id, project_id, state, raw_data) as disabled inputs — they are excluded
-from the form and preserved on save — and the form now defaults to being
-toggled open. Task labels render as read-only badges in the detail view
-instead.
