feat(documents): pick documents from Paperless-ngx or Papra in the vault and wherever documents are linked

A settings card under Integrations connects either system and tests it
before saving. An import button beside Upload in Documents, on a
condition's documents card, and beside Add in the visit and vaccination
document pickers opens a sheet that searches by name with tag and date
filters, shows what HealthLog already holds, and imports the ticked
documents one at a time with a result per row. The buttons appear only
for a person in their own record with a connection; strings in all
seven languages.

+ * The document picker (#1038): search a connected Paperless-ngx or Papra by

+ * import them.
+ *
+ * Name first, because that is how the person looks for a letter: the search
+ * field opens focused and debounces into the source's own name search. Tag and
+ * date are filters beside it, not the entry point. Each result says what
+ * HealthLog already holds under that source key: already imported, deleted
+ * here (not offered again: a deletion was a decision), or new.
+ *
+ * The import runs one document per request, in order, so every row can show
+ * its own progress and result, and one failure does not hide the others. A
+ * refusal that will answer every following document the same way (the hourly
+ * upload allowance, a full vault, a refused token) stops the run and says so.
+ *
+ * Where it was opened from decides what an import does besides storing:
+ *
+ *   - `link`: the record already exists (a condition's page), so the server
+ *     files the document against it as part of the import;
+ *   - `onImported`: a form that owns its selection (a visit, a vaccination)
+ *     gets the new ids and adds them itself. Linking on the server there would
+ *     be undone by the form's own save, which replaces its links.
+ *
+ * With either, a document already in HealthLog can be picked too: it is not
+ * stored twice, it is linked or handed to the form.
