[PR] [core] Read the table branch schemas when rewriting file indexes [paimon]

plusplusjiajia opened a new pull request, #9468:
URL: https://github.com/apache/paimon/pull/9468

     ### Purpose
   
     `FileIndexProcessor` looks up the schema of every file it rewrites through a `SchemaManager` pinned to the main branch, while the manifest entries it processes come from the table it was given. Running `rewrite_file_index` on a branch therefore resolves the branch's schema ids under main: it reads a different schema when both branches happen to have that id, and fails with `FileNotFoundException: .../schema/schema-N` when main never had it.
   
     ### Tests
   
     `FileIndexProcessorTest`: a branch whose schema id exists only on the branch is processed successfully; without the change the lookup throws.
