Add topics to Composers and smarter default clip colours

Composers get easier to set up. Create empty topics, get a warning before a mixed vault upload, and enjoy new clips that automatically inherit the right colour.

New Features ⭐️

• Add New Topic button added to Composers, allowing users to create empty topics more easily.
• New warning added during Vault uploads:

“Package should not contain more than one timeline or composer” — triggered when multiple file types are detected.

Improvements 🔨

• Restarting the Upload Hours Start period now clears the graph of stats from the previous period.
• Reordered sections in the File Management sidebar for improved usability.
• Default clip colour when creating a new clip now inherits:
• The row colour, if set; or
• The most common colour from existing clips in that row, if no row colour exists.

Bug Fixes 🐞

• Fixed issue where the sharing modal wasn’t displaying groups that had already been shared to.
• Added safeguards to ensure all newly uploaded files have a valid file type stored in the database — critical for proper access in the iOS and Android apps.
