Fix filter dropdowns returning empty string for All option

The build passes. The fix I implemented:

1. **Changed the API type** in `Omni/Jr/Web.hs` to use `QueryParam
"stat 2. **Added manual parsing** in `taskListHandler` with
`parseStatus` and 3. **Applied `emptyToNothing`** to both status and
priority params befor

This ensures that when "All" is selected (empty string), it's
treated as

I also fixed two pre-existing issues that were blocking the build:
- Type annotation for `show stage` in `Omni/Task/Core.hs` -
`AesonKey.fromText` conversion in `Omni/Agent/Worker.hs`
