Upload script (migrated JSON to Weblate)

[AuraMindNest]

Problem

Corrected translation component JSON files sit on disk with no automated mechanism to push them to the target Weblate instance.

Acceptance Criteria

• CLI script reads corrected component JSON from disk and pushes to Weblate via REST API
• Handles authentication, error reporting, and idempotent re-runs
• Documented usage
• PR approved by at least 1 reviewer
