Add missing migration for Meta options on Subtitle, TranscriptionRequest, and VideoTrimRequest (#1448)

Fixes #1447

This migration adds the missing AlterModelOptions operations for:
- Subtitle model (verbose_name: 'Caption', verbose_name_plural: 'Captions')
- TranscriptionRequest model (verbose_name: 'Caption Request', verbose_name_plural: 'Caption Requests')
- VideoTrimRequest model (verbose_name: 'Trim Request', verbose_name_plural: 'Trim Requests')

These Meta options were defined in the models but never migrated, causing
makemigrations --dry-run to show pending migrations on fresh clones.
