Patient everything inline attachments (#9481)

* feat(server): inline DocumentReference attachments in Patient \$everything

Adds a `_inlineAttachments=true` query parameter to the Patient `\$everything`
operation. When enabled, DocumentReference attachments that point to Binary
storage are fetched and embedded as base64-encoded `attachment.data` in the
response, removing the `attachment.url`.

A `_maxAttachmentSize` parameter (bytes, default 10 MB) caps which attachments
are inlined. Attachments exceeding the limit keep their storage URL. The stream
is read incrementally and abandoned early when the cap is hit, avoiding full
reads of oversized files.

The `normalizeBinaryUrl` helper in rewrite.ts is exported so it can be reused
by the new inlining logic.

The Patient Export form in the UI gains an "Inline attachments" checkbox and a
max-size input (in MB) under the FHIR Everything format option.
