Adds Tag.kind enum (artist/character/fandom/general/series/archive/post/meta/rating), Tag.fandom_id FK with CHECK constraint (only valid for kind='character'), and a kind-aware uniqueness index so the same name can exist across kinds and the same character name can exist in different fandoms. Adds ImportBatch + ImportTask state-machine tables for scan tracking, plus a single-row ImportSettings table (CHECK id=1) holding the importer's filter knobs. Adds image_record.integrity_status column (defaults to 'unknown'); FC-2e populates this via the integrity verifier. Drops the unused tag.namespace column from FC-1 — superseded by kind.

"""ImportTask — a single source file to import as part of a batch.

State machine: pending -> queued -> processing -> complete | skipped | failed.

Workers crashing mid-task leave rows in 'processing'; the recovery sweep

(tasks/maintenance.py::recover_interrupted_tasks) re-queues rows that have

been processing longer than the stuck-task threshold.
