Data Fixes & Migrations

Scans recordings with missing model links and attempts to find the corresponding model by matching source and username.

Updates `lastVideoDate` for all models based on the maximum `recordedAt` date from their linked recordings. Fixes sorting order.

Converts legacy gender strings (Male, Female, etc.) to standard codes (m, f, c, t).

Repairs broken image URLs for specific providers (fastimages.org, etc.).

Creates default ELO ratings (1500) for all models that don't have one.

Fetches all models from CamsHQ API in bulk and enriches local models that need it. Much faster than individual enrichment (~3-4 min vs hours).
