Implement live syncback fixes addressing multiple issues

- Added explicit encoding for Workspace attributes and tags in `encodeService.lua` to prevent data loss during syncback.
- Filtered non-serializable properties, including `ClockTime`, in `build_dom_from_chunks` to ensure accurate data handling.
- Resolved a leak of `Rojo_Ref_CurrentCamera` by filtering deferred referents after camera destruction in `syncback_loop`.
- Truncated float values to f32 precision in `UnresolvedValue::from_variant` to match rbxl storage format, improving data consistency.

These changes enhance the reliability and accuracy of the live syncback process, addressing critical issues identified in previous implementations.
