* fix(memory): jsonify metadata before Prisma writes on /v1/memory
The POST/PUT memory endpoints handed bare dicts (and bare `None`) to
prisma-client-python for the `Json?` `metadata` column, which the client
rejects with `MissingRequiredValueError` / `DataError: metadata should
be of any of the following types: NullableJsonNullValueInput, Json`.
Both the create and upsert paths now route writes through the existing
`jsonify_object` helper used elsewhere in the proxy for `Json?` columns
(e.g. `LiteLLM_VerificationToken.budget_limits`), and omit metadata
when None so the column defaults to SQL NULL via the schema.
Explicit `metadata: null` on PUT is now a no-op for the column to match
how the rest of the proxy handles nullable JSON fields (no
`JsonNull`/`DbNull` sentinel exists in prisma-client-python — see
RobertCraigie/prisma-client-py#714). A payload with only `metadata: null`
returns 400 instead of a misleading 200.

* fix(memory): JSON-encode non-dict metadata before Prisma writes
`jsonify_object` only stringifies dict values, so list-shaped metadata
still hit Prisma as raw Python objects and triggered the same
DataError this PR is meant to fix. `metadata` is typed `Optional[Any]`
so list payloads are valid input. Replace `jsonify_object` with a
local `_serialize_metadata_for_prisma` helper that always `json.dumps`
non-string values, applied at all three write sites
(POST create, PUT update, PUT-create). Adds regression tests for
list metadata on each path.

* fix(memory): always json.dumps metadata, not just non-strings
The str-passthrough in `_serialize_metadata_for_prisma` left plain
Python strings (e.g. `metadata: "hello"`) unencoded — Postgres `jsonb`
rejects bare-word strings as invalid JSON, reproducing the same
DataError this PR is meant to fix. Always `json.dumps` regardless of
input type so all `Optional[Any]` shapes (dict, list, scalar, str)
become valid JSON. Adds a regression test for plain-string metadata.
