feat(ms): import mzML chromatograms and MRM transitions

[nmrtist]

Summary

• Import mzML chromatogramList data, including TIC, BPC, SIM, and SRM channels, and support valid chromatogram-only acquisitions that contain no spectra.
• Preserve chromatogram kind, polarity, and structured transition metadata (precursor/product m/z, collision energy, and activation method) through the existing field, chart, project, and scientific-summary paths. The unpublished v1 mass-spec payload is updated in place, with no draft-format compatibility reader.
• Avoid rebuilding the complete mass-spec field catalog for each field lookup. This keeps a 722-channel scheduled-MRM run responsive instead of performing allocation-heavy quadratic work on the UI thread.
• Treat declared mzML non-standard data arrays as optional auxiliary data while retaining warnings for genuinely unknown required arrays. Update the English and Simplified Chinese import documentation accordingly.

Validation

• cargo pr-check
• cargo test -q -p plotx-io mzml -- --nocapture (14 passed)
• cargo test -q -p plotx-core mass_spec -- --nocapture (31 passed)
• Inspected public PXD066465 scheduled-MRM mzML: 0 streams, 0 scans, 722 chromatograms (TIC, BPC, and 720 SRM transitions), with no auxiliary-array import warnings.
• Inspected public MTBLS12824 negative-mode mzML: 1 stream, 1,231 MS1 scans, negative polarity, TIC, and BPC.
• Manually opened and exercised the scheduled-MRM fixture: channel/transition summaries, plotting, project round-trip, sidebar/canvas interaction, and UI responsiveness behaved as expected.

UI display logic

• No new or changed global actions; command-catalog behavior is unchanged.
• No Ribbon visibility or transient command-state changes.
• No background-driven layout changes or automatic panel closing.
• Existing mass-spec views retain their established empty-state behavior.
• Docs updated in docs/ (English and zh-CN) for user-visible behavior.
