Filter applied with invalid range input (Number and Date from/to widgets)

[RastoHu]

Description

When a Number (from/to) or Date (from/to) filter is configured with an invalid range (Min > Max / From > To), the app shows a validation error but still allows the filter to be submitted. Tapping "Apply filters" applies the filter and returns 0 features instead of blocking submission.

Environment

• PROD

Application (+ app version, build, operating system)
Mergin Maps iOS 2026.2.0 / iOS 26.4

Steps to reproduce

1. Open a project with a Number (from/to) filter configured
2. Open Filters → Number filter → enter Min = 100, Max = 10
3. Observe the validation error → tap Apply filters
4. Open the layer features list
5. Repeat for a Date (from/to) filter → set From = 01/05/2026, To = 20/04/2026 → Apply filters

Actual results

• Validation error "Min" must be less than "Max" / "From" must be sooner than "To" is shown under both fields with red borders
• Apply filters button remains active and filter is submitted
• 0 features returned; "Active filters applied" banner shown in the features list

Expected results

• Apply filters button should be disabled when a validation error is present
• Filter should not be submitted until the range is corrected
