refactor: next-for-review api refactor with multiple parameters for filtering

API Issue Template

Title (semantic)

refactor(api): Updated next-for-review to fetch the records based on parameter based filters.

Description

Get the next record(s) for review.

This endpoint can operate in two modes:

1. Proofreading mode (proof_reading=True): identifies records that have pages (segments) that have not been proofread.
2. Random mode (proof_reading=False): fetches records randomly with optional filters.

Filters:

• Excludes user's own records.
• Optional language and media type filtering.
• Random selection from the available records.

Checklist

• Code follows project API guidelines.
• Tests for API endpoints are included and passing.
• API documentation is updated (if applicable).
• Performance considerations have been addressed.
