refactor(presence): convert presence to use source

[cngonzalez]

Description

Presence as it's implemented in the SDK right now doesn't seem to work for Canvas or Media Library (we get a Websocket error) but we still need to move it to source for architectural reasons. This PR does that.

What to review

• The updated presenceStore.ts implementation which now validates source types
• The modified usePresence hook that accepts source options and validates them
• Test coverage for both supported and unsupported source types
• Error messages that provide clear guidance when using unsupported sources

Testing

Added comprehensive tests for:

• Validating that dataset sources work correctly
• Ensuring appropriate error messages when using media library sources
• Ensuring appropriate error messages when using canvas sources
• Verifying existing functionality continues to work with the new parameter structure
