Auto translate strings

* Perf: batch the repeated lookups in modify_custom_fields

`modify_custom_fields()` re-resolved the same objects inside its
per-document loop: `custom_fields.get(id=field_id)` re-ran a CustomField
query for every document, and doc link fields called
`Document.objects.get(id=doc_id)` a second time for a document that was
already known.

Resolve both up front with `in_bulk()` and hand the resolved objects to
`update_or_create()` rather than bare ids. Passing the objects also
populates the FK cache on the newly created instance, so auditlog's
post_save receiver touching `.document`/`.field` no longer costs a reload
per row. The document map defers `content`, the one field here that is
both large and unused. The symmetrical-link removal pass and
`remove_doclink()` get `select_related()` for the same auditlog reason.

Measured over 50 documents, sqlite, audit log enabled:

                        before   after
  add 3 string fields    1502    1054
  update 1 string field   451     403
  add doc link            851     653
  remove doc link         604     354

`update_or_create()` is kept as-is. Dropping it for a hand-rolled
get-or-construct loop removes a further ~4 statements per row, but those
are the SAVEPOINT/RELEASE pairs of its `transaction.atomic()`, and the
`select_for_update()` and IntegrityError fallback that go with them. The
(document, field) unique constraint depends on that when two bulk edits
overlap, and the wall clock did not move to pay for it (331 ms vs 310 ms
for the string case above).

Also normalises the field ids to int once at the top so the old dict API,
whose keys may arrive as strings, indexes the resolved map correctly.

The `if custom_field:` branch it replaces was dead: `.get()` raises
DoesNotExist, it never returns None.
