Fix broken links

[mintlify]

Summary

Resolves all 149 broken links reported by mint broken-links across the docs (58 files).

Changes

• synforecast (46 files, 121 links): converted relative in-repo links (e.g. changepoints, ../getting-started/quickstart, ../generators/multivariate/var) to root-relative URLs with the .html suffix (e.g. /synforecast/docs/capabilities/changepoints.html), matching the paths registered in docs.json.
• synforecast/docs/integrations/nixtlaverse.html.mdx: replaced three broken .ipynb references with the corresponding root-relative .html integration pages.
• mlforecast/lag_transforms.html.mdx: rewrote two relative guide links (docs/how-to-guides/lag_transforms_guide.html, docs/how-to-guides/pooled_lag_transforms.html) as root-relative /mlforecast/docs/how-to-guides/... URLs.
• neuralforecast/docs/tutorials/comparing_methods.html.mdx: replaced ../../../statsforecast/models.html with /statsforecast/src/core/models.html (the actual registered page).
• neuralforecast/losses.numpy.html.mdx: switched 8 imgs_losses/*.png image refs to root-relative /neuralforecast/imgs_losses/....
• neuralforecast/models.nbeatsx.html.mdx: fixed a duplicated ./neuralforecast/models.nbeats.html#nbeats-2 link (wrong path + missing anchor) to ./models.nbeats.html#nbeats.
• neuralforecast/models.softssharp.html.mdx: made the SOFTSSharp figure link root-relative (/neuralforecast/imgs_models/softssharp.png).
• statsforecast/docs/experiments/autoarima_vs_prophet.html.mdx: rewrote 6 AutoArima_vs_Prophet_files/... image refs as root-relative paths.
• statsforecast/docs/tutorials/electricitypeakforecasting.html.mdx: repointed ../../../neuralforecast/use-cases/electricitypeakforecasting.html to the actual page /neuralforecast/docs/use-cases/electricity_peak_forecasting.html.
• statsforecast/docs/tutorials/statisticalneuralmethods.html.mdx: repointed ../../../neuralforecast/tutorials/getting_started_complete.html to /neuralforecast/docs/tutorials/getting_started_complete.html.
• utilsforecast/index.html.mdx: removed the extra broken ./docs/mintlify/imgs/index.png reference (the same figure is still shown via ./imgs/index.png).
• utilsforecast/plotting.html.mdx: made the imgs/plotting.png reference root-relative.

Missing assets — left as TODO notes

Two referenced images do not exist anywhere in the repo. Rather than guess at replacements, they were replaced with {/* TODO */} notes so a human can restore the correct asset:

• neuralforecast/imgs_models/stemgnn.png (Figure 1 in neuralforecast/models.stemgnn.html.mdx).
• statsforecast/imgs/cv-sphere.png (figure in statsforecast/docs/tutorials/statisticalneuralmethods.html.mdx).

Validation

• mint validate → build validation passed.
• mint broken-links → no broken links found.
