Add stream-based floating tags for dev versions#504

Dev versions from named release streams (daily, preview) now
automatically get floating tags using the stream name. For example,
a Connect daily build produces tags like `daily`, `daily-ubuntu-24.04`,
and `daily-std` alongside the versioned tags.
This replaces the old `ubuntu2204-daily` style floating tags that
were managed outside of bakery. The stream name is already stored
in ImageVersion metadata — this change exposes it to the tag
template system.
- Add `Stream` to tag template values from version metadata
- Add `{{ Stream }}`-based patterns to default tag patterns
- Skip rendering when Stream is empty (release versions)
The Stream extraction used getattr(..., "value", "") which silently returned empty string for plain-string metadata. Now handles both enum and string forms. Adds positive test covering enum, string, and absent release_stream metadata.
