Office ID is Case Sensitive and returns empty timeseries group if wrong case is input

[msweier]

Describe the bug
At timeseries group endpoint, the office ID is case sensitive for the owning office. If the wrong case is provided an empty group is returned.

Expected behavior
I would expect some sort of error stating that the group couldn't be found.

To Reproduce

curl -X 'GET' \
  'https://DEV/cwms-data/timeseries/group/Web?office=mvp&category-office-id=mvp&group-office-id=mvp&category-id=MVP%20Dissemination&_cb=1770150293517' \
  -H 'accept: application/json' \
  -H 'Cache-Control: no-cache, no-store, max-age=0' \
  -H 'Pragma: no-cache'

returns

{
  "office-id": "MVP",
  "id": "Web",
  "time-series-category": {
    "office-id": "MVP",
    "id": "MVP Dissemination"
  },
  "assigned-time-series": []
}

Where

curl -X 'GET' \
  'https://DEV/cwms-data/timeseries/group/Web?office=MVP&category-office-id=MVP&group-office-id=MVP&category-id=MVP%20Dissemination&_cb=1770151790542' \
  -H 'accept: application/json' \
  -H 'Cache-Control: no-cache, no-store, max-age=0' \
  -H 'Pragma: no-cache'

returns the group as expected.
