chore: update versioning and enhance training unit features

- Incremented APP_VERSION to 0.8.10 and DB_SCHEMA_VERSION to 20260505037.
- Added changelog entry for version 0.8.10 detailing database and API changes.
- Refactored training framework program handling to support cloning training units from framework slots.
- Improved permission checks for training units based on framework slot associations.
- Introduced new API endpoint for creating training units from framework slots.
