### What problem does this PR solve?
Fixes#12570 - The slicing method dropdown was empty when deploying
RAGFlow v0.23.1 from source code.
The issue occurred because `parser_ids` from the tenant info was empty
or undefined, causing `useSelectParserList` to return an empty array.
This PR adds a fallback to a default parser list when `parser_ids` is
empty, ensuring the dropdown always has options.
