Accept the option picked in selects of translatable records

Saving a page with a category failed with "El campo categoría no está
en la lista de valores permitidos" — for every category, not only the
one being tried. Filament builds such a list through a query, which
handles `->relationship('category', 'name->es')`, but validates a choice
by reading the title back off the record as a property,
`$record->{'name->es'}`, which does not exist. No label, so every
option was refused.

The same pattern was in seven more places: a call's, a testimonial's,
a talk's and a repository's project, a testimonial's service, and the
page and application filters. TranslatedOptionLabel gives Filament the
record's own translation instead, in the language of whoever uses the
panel; the JSON path stays for search and ordering.
