feat: Reduce `put` time

[thomass-dev]

• Only push permutations if they are computed (#2094)
• Use the hash generated by skore to upload a report (#2114)
• Parallelize media upload (#2114)
• Retrieve media from report's cache generated by skore
• Serialize intelligently reports

@thomass-dev don't hesitate to open sub-issues: I feel that "Serialize intelligently reports" would require some digging and maybe having its own issue before to go to the implementation then it will be easier.
