Inconsistent results for user quota when using `default_quota`

Steps to reproduce

1. Give a value to default_quota in the server, ex "1 GB"
2. Have user user1 assigned the value of default_quota. Verify it too by checking user1 settings page.
3. Run:

Case 1:

# occ usage-report:generate --output=json user1 | jq .quota`
0

Case 2:

# occ usage-report:generate --output=json | grep user1 | jq .quota`
"1 GB"

Expected behaviour

The field quota should be always an integer number and consistent.

Actual behaviour

The field quota is wrong (case 1) and a string (case 2). Manually assigning the user the same value as default_quota fixes the issue.

Start with the occ usage-report:generate --output=json entry point and trace how quota is calculated for a named user versus the bulk report, especially when default_quota is inherited. Reproduce both commands with a user assigned the server default, then verify that quota is consistently emitted as an integer in both outputs.
