chore: capitalize brand name as DeepLethe across project metadata (#9)

The company brand is DeepLethe (camelCase), not deeplethe. Fixed the
lowercase occurrences in the public-facing author/affiliation fields:

- docs/paper/main.tex: \affil[1]{DeepLethe}
- firmware/esp32/library.properties: author / maintainer
- pyproject.toml: authors[].name (shows on the PyPI project page)
- docs/paper/README.md: submission-checklist reference

Not touched: examples/smart_panel_manifest.yaml still has
`vendor: deeplethe`, which is a separate question — the `vendor`
field elsewhere (lamp) uses a domain form (example.dev), so that one
should likely become a domain rather than just be recapitalized.
