- Remove conflicting `analysis = "..."` scalar from [nav] in both
en.toml and pt.toml; it shadowed the [nav.analysis] sub-table,
causing the TOML parser to reject the entire file at startup
- Update nav analysis dropdown label to reuse nav.drawer.analysis_label
- Add lang field to Translator and expose T.Lang() method so base.html
can highlight the active language in the switcher without requiring
a Lang field on every page data struct
