[Docs] Fix inline backticks in API CN docs (batch 3)

[ghost]

Summary

• Batch-fix invalid single-backtick inline literals in Chinese API docs.
• Replace invalid `...` inline literals with ``...`` where appropriate.
• This batch is on a new branch and does not overlap with PR [Docs] Batch fix single-backtick inline literals in API CN docs #7869 target files.

Scope

• 25 files under docs/api/paddle/**.
• Focused on sparse, optimizer/lr, static, distribution, and related docs.

Validation

• Checker: output/check_rst_single_backticks.py.
• Re-scanned all modified files and confirmed target files are clean.

Notes

• Keep as draft for potential incremental follow-ups.
