docs(notebooks): port compute qmd notebook fixes

[marcorudolphflex]

Summary

• Port the compute-side Autograd12LightExtractor.qmd history filename fix back into the source notebook: misc/qe_light_coupler_autograd.pkl -> misc/qe_light_coupler.pkl.
• Port the compute-side ChargeSolver.qmd Palankovski & Quay carrier lifetime update back into the source notebook.
• Add spelling dictionary entries for the transferred ChargeSolver API terms.

Why

These edits were made directly in compute qmd files after the Quarto migration, but they were not present in tidy3d-notebooks on develop or pre/2.12. Keeping them only in generated qmd files makes future notebook-to-qmd syncs regress those docs.

The related compute changes were:

• flexcompute/compute#5392 by Dario: Autograd12LightExtractor.qmd history filename fix.
• flexcompute/compute#5322 by Marc: ChargeSolver.qmd Palankovski & Quay carrier lifetime docs/code update.

The Autograd23FabricationAwareInvdes.qmd change from compute was whitespace-only generated qmd cleanup, so there is no source-notebook change to port.

Validation

• python3 -m json.tool Autograd12LightExtractor.ipynb ChargeSolver.ipynb custom_dictionary.json
• uvx ruff==0.14.1 format --check --diff Autograd12LightExtractor.ipynb ChargeSolver.ipynb
• uv run --no-project python scripts/validate_notebook_metadata.py Autograd12LightExtractor.ipynb ChargeSolver.ipynb
• uv run --no-project ./spellcheck.py Autograd12LightExtractor.ipynb ChargeSolver.ipynb
• python3 misc/check_misc_references.py
• uv run --no-project python scripts/sync_metadata_tags.py --check
• git diff --check origin/pre/2.12..HEAD

Note: spellcheck prints existing invalid-metadata messages from unrelated reference notebooks while building its dictionary, but exits successfully for the changed notebook set.

Note

Low Risk
Documentation-only path string in a notebook; no runtime, auth, or API behavior changes.

Overview
Ports a compute-side Quarto doc fix back into the source notebook by renaming the optimization history file from misc/qe_light_coupler_autograd.pkl to misc/qe_light_coupler.pkl.

save_history / load_history still use the same history_fname variable—only the path string changes so future notebook→qmd syncs match the published docs and bundled misc asset name.
