Pre-merge checks and finishing touches

✅ Passed checks (7 passed)

Check name	Status	Explanation
Description Check	✅ Passed	Check skipped - CodeRabbit’s high-level summary is enabled.
Title Check	✅ Passed	The title accurately reflects the addition of a troubleshooting section for Pydantic request body mismatches in the documentation, aligns with the changes made, and follows a clear, concise conventional commit format.
Docstring Coverage	✅ Passed	No functions found in the changes. Docstring coverage check skipped.
Test Coverage For New Implementations	✅ Passed	The PR modifies only documentation (docs/docs/Support/troubleshooting.mdx) and introduces no new functionality, bug fixes, or code changes, so there is no need for accompanying tests and consequently no missing test coverage to report.
Test Quality And Coverage	✅ Passed	The pull request only updates documentation to add troubleshooting guidance and makes no modifications to runtime code or testing targets, so there is no new functionality requiring automated tests. Existing test coverage remains unaffected, and the absence of additional tests is appropriate for a doc-only change.
Test File Naming And Structure	✅ Passed	Repository inspection reveals that backend tests are named with the pytest-compliant test_*.py convention, frontend tests use the expected *.test.ts(x) suffix with Playwright helpers, integration tests reside under dedicated integration directories, and sampled test functions exhibit descriptive naming, structured setup/teardown, and coverage of both positive and negative scenarios, indicating adherence to the required patterns.
Excessive Mock Usage Warning	✅ Passed	No test files were modified in this pull request—only documentation was changed—so there is no new or altered test code using mocks to evaluate; therefore the check passes by default.
