Testresults module: form-based parameter binding, UserSchema registration, and Selenium tests (#622)

- `TestResultsSchema `extends UserSchema with DefaultSchema.registerProvider() registration, FK lookup columns, and wrapAllColumns() in createTable()
  - _Post-deploy_: Delete external schema on skyline.ms since the code-level registration now supersedes it. 
- Added form classes replacing all request.getParameter() calls across all actions
- Integer/Boolean for optional form parameters with null guards and descriptive error messages
- ParseException handling with SimpleErrorView for date parameters
- `cause` field added to error API responses; JSP alert messages updated to display it
- Added addNavTrail overrides to prevent missing page title warnings
- New `TestResultsTest` Selenium test class covering begin page, show run, run lookup, user runs, long-term trends, failures, flagging, and training data workflows
  - `BeginAction` (rundown page, date navigation, viewType selector)
  - `ShowRunAction` (run detail, pass sorting)
  - `ShowUserAction` (user page, date range)
  - `LongTermAction` (viewType selector)
  - `ShowFailuresAction` (failure detail, viewType selector)
  - `FlagRunAction` / `ShowFlaggedAction` (flag/unflag workflow)
  - `TrainRunAction` / `TrainingDataViewAction` (add/remove training set workflow)
  - `ViewLogAction` (view run log)
  - `ViewXMLAction` (view run XML)
  - `ChangeBoundariesAction` (update warning/error boundaries)
  - `SetUserActiveAction` (activate/deactivate user)
  - `DeleteRunAction` (delete a run)
- Replaced deprecated `javax.management.modelmbean.XMLParseException` with `IllegalArgumentException`
- Switched from `org.springframework.util.StringUtils` to `org.apache.commons.lang3.StringUtils`
