Ran clang-format on all 134 CPP files in src/ using the project's
.clang-format config
#### Motivation for adding to Mudlet

None
**Test case:** Build the project and verify it compiles successfully.
#### Brief overview of PR changes/additions
- Wrap all `qWarning()` and `qDebug()` statements in undo/redo command
files with `#if defined(DEBUG_UNDO_REDO)` guards
- Affects EditorDeleteItemCommand, EditorModifyPropertyCommand,
EditorAddItemCommand, EditorUndoStack
#### Motivation for adding to Mudlet
Prevents debug spam in console output during normal usage while keeping
messages available when explicitly enabled for development.
#### Other info (issues closed, discussion etc)
**Test case:** Build and run Mudlet, perform undo/redo operations in the
editor - no debug messages should appear in console. Enable
`DEBUG_UNDO_REDO` in CMakeLists.txt to verify messages still work when
needed.

#### Brief overview of PR changes/additions
Adds undo/redo for Mudlet editor - allows you to undo
adding/changing/deleting triggers, aliases and so on. This PR also adds
visual tests that can be run inside the `Mudlet self-test` profile, and
they are hooked up to run in the CI pipeline automatically. The deletion
confirmation dialog has been itself deleted since we can now undo.
#### Motivation for adding to Mudlet
Long-awaited and often requested feature. Fixes#707 and addresses
#8272.
#### Other info (issues closed, discussion etc)
This test also adds 300+ tests that can be run in the Mudlet self-test
profile (launch it from the CLI using `--profile "Mudlet self-test"`):
