label "Read and confirmed" for "Read and Sign" envelopes.
- Added `DocumentSignedRaC` resource key to `Model.resx` and
`Model.en.resx` with localized values ("Gelesen und bestätigt"
and "Read and confirmed").

to reflect changes, including testing steps and task completion.
These changes ensure accurate status labels in the report for
different envelope types.
