CI: update main and add uv support

[daywalker90]

• Support uv projects, refactored the explicit tmp directory creation to not run for uv projects
• Update python 3.12 to 3.13 in the matrix (torq-plugin needs to update dependencies for 3.13)
• Detect poetry and uv projects by their .lock files to differentiate them (if both are present due to migration prioritize uv)
• Don't check out lightning repo and pull the published pyln-* packages instead with the matching version to CLN
• Save cache more often, they get deleted after a week anyways and it speeds up PR runs

clnrest-rs sometimes runs very long i don't know why. The timeout then exceeds the action timeout, and the job gets cancelled. We will archive clnrest-rs with v25.09 anyways so that's how i'd fix it.
