fix(ci): restore master validation checks

[sadpandajoe]

SUMMARY

Restore three deterministic checks found while walking master CI back to the last three-commit green boundary:

• Apply the repository formatting emitted by oxfmt 0.61 after chore(deps-dev): bump oxfmt from 0.60.0 to 0.61.0 in /superset-frontend #42746 upgraded the formatter without a full-tree formatting pass.
• Preserve APP_ROOT in the version-history activity-log Playwright test by using the existing apiGet helper with relative URLs. The old leading-slash requests returned 404 in the required /app/prefix project after feat(versioning): version-history UI #41551.
• Freeze the MCP sub-day time-range parser premise away from midnight. The production-normalizer assertions remain unchanged; only the clock-dependent raw-parser setup introduced by Timeseries Bar: stacked 'Only Total' sum includes the series-limit/sort metric's value, not just the displayed metrics #42701 becomes deterministic.

The fixes remain three independent commits. They are consolidated because a required all-files pre-commit run from the affected master baseline necessarily includes the formatter rewrite.

BEFORE/AFTER SCREENSHOTS OR ANIMATED GIF

Not applicable; these are CI/test and formatting corrections with no UI behavior change.

TESTING INSTRUCTIONS

• SKIP=type-checking-frontend pre-commit run --all-files using the workflow's Python 3.11/ruff 0.9.7 and Node 24.16/npm 11.13 toolchain
• oxfmt --check across all 3,769 frontend files after applying the formatter changes
• oxlint --config oxlint.json --quiet playwright/tests/version-history/activity-log.spec.ts
• playwright test playwright/tests/version-history/activity-log.spec.ts --list
• Verify relative API URLs resolve below http://127.0.0.1:8081/app/prefix/
• ruff format --check tests/unit_tests/mcp_service/common/test_time_range_validation.py
• ruff check tests/unit_tests/mcp_service/common/test_time_range_validation.py
• python -m py_compile tests/unit_tests/mcp_service/common/test_time_range_validation.py

The targeted MCP pytest could not run in the host environment because its globally installed sqlglot predates the singlestore dialect imported by this checkout. Required GitHub checks use the repository's pinned dependencies and are monitored to terminal state.

@sadpandajoe LGTM. Confirmed the 20 reformatted files are pure whitespace, oxfmt getting a full-tree pass makes sense. The relative-URL playwright fix and the frozen-clock MCP test are both solid, small fixes for what they're chasing.
