fdac249d82 docs(spec): clarify essentials_category presence rules
The previous description said "null for nodes that don't set
ESSENTIALS_CATEGORY (V1)" — that's wrong. server.py:739-740 uses
`hasattr` and OMITS the key when the V1 attribute isn't defined; null
only happens if the attribute is explicitly set to None. Spell out
all three legal shapes (string / null / absent) and which path
produces which.

5a316da613 fix(spec): mark DeviceStats.index and NodeInfo.essentials_category as nullable
Two fields in openapi.yaml are declared as required/non-nullable but
the Python implementation legitimately returns `null` for them, so any
client that response-validates against the spec will fail.

`DeviceStats.index` (used by GET /api/system_stats):
- server.py emits `"index": device.index` unconditionally
- For the CPU device (--cpu mode), `torch.device("cpu").index` is `None`
- → JSON response includes `"index": null` for CPU devices

`NodeInfo.essentials_category` (used by GET /api/object_info):
- The V3 schema-based path (comfy_api/latest/_io.py:1654) unconditionally
  passes `essentials_category=self.essentials_category` into NodeInfoV1
  and serializes via dataclasses.asdict(), so the key is always present
- Schema's `essentials_category` defaults to `None` for nodes that
  don't set it in `define_schema` (e.g. the APG node)
- → JSON response includes `"essentials_category": null` for those nodes
- (The V1 path in server.py uses `hasattr` and so omits the key
  entirely when not set, but the V3 path is the one that produces nulls)

Both fields keep their existing `required` status — they're always
present in the response, the value is just nullable. Descriptions
expanded to spell out when `null` is expected.
