Fix unit endpoint routes

[jsachs]

Problem

The NERIS API defines these unit endpoints:

POST  /entity/{neris_id_entity}/station/{neris_id_station}/unit
PATCH /entity/{neris_id_entity}/station/{neris_id_station}/unit/{neris_id_unit}

The client’s create_unit method omitted /unit and instead posted to the station resource. This sends a unit payload to the wrong endpoint.

patch_unit also referenced an undefined neris_id variable when building its URL. Any call to this method raises NameError before making an HTTP request.

Fix

• Send unit creation requests to the documented /unit collection route.
• Build the unit patch route using the supplied neris_id_entity parameter.

Example

client.create_unit(
    "FD24027334",
    "FD24027334S001",
    {
        "staffing": 4,
        "type": "...",
        "cad_designation_1": "ENGINE 1",
    },
)

Now sends:

POST /entity/FD24027334/station/FD24027334S001/unit

client.patch_unit(
    "FD24027334",
    "FD24027334S001",
    "FD24027334S001U003",
    {"staffing": 5},
)

Now sends:

PATCH /entity/FD24027334/station/FD24027334S001/unit/FD24027334S001U003

Tests

• Added regression tests for both generated routes.
