feat(autocomplete): aliases, extra-networks, translations, baseline fixes

- tag aliases (optional 4-tuple) and translations (companion file)
- lora and wildcard triggers; embeddings fold into tag-mode results
- new GET /sdapi/v1/wildcards endpoint
- LRU cap, IME safety, multi-textarea safety, modifier-key pass-through
- manifest-retry and config-bridge hardening
- tags-fetch: alias/translation harvesters with authenticated rate limits
