feat(wizard): optional AcoustID key step for metadata enrichment

Adds a wizard step (after the ML step) that prompts for an AcoustID API
key. Left blank, enrichment runs on embedded tags only; with a key the
backend also identifies untagged files by audio fingerprint (§1D). The
key is appended to .env.deploy and reaches both api and worker via
env_file. en/ru strings included.
