FIREFLY-2117: Restrict spectral charts xaxis range when spectral lines go outside data range

[jaladh-singhal]

Fixes FIREFLY-2117

Spectral lines far outside the data (e.g. Herschel far-IR lines on a 5–9 µm Spitzer spectrum) stretched the x axis to ~650 µm, since Plotly counts shapes in autorange with no per-shape opt-out. Added makeShapesAutorangeLayout (ChartUtil.js), which clips x autorange to the padded data extent using Plotly's autorangeoptions.clipmin/clipmax, so autorange (initial plotting, 1x button, filter resets) still fits the data while lines beyond it still show when zoomed out.

Testing

• Upload a spectrum (Spitzer_IRS_SL_PBCD-topocenter.vot in ticket) -> Spectral lines dialog -> load Spitzer PAHFIT + Herschel HSPOT -> x axis should fit the data, not the lines unlike the screenshot in the ticket.
• Zoom in -> 1x: back to the data range; filter the table (e.g. wavelength < 6.5): axis shrinks to the filtered data
• Deselect all lines: normal autorange returns; reselect: clipped again
• Chart Options: X Min/Max wider than the data (e.g. 3–12) should be applied as is, showing lines beyond the data; also check observed/rest frame with a redshift (e.g. 0.4), reverse and log
• Regression: a non-spectrum chart (no lines) is unaffected

Tested and it worked as described. Changes look good. Ready to go.
