* fix(security): replace new Function() with safe math expression parser
Replace the dangerous new Function() constructor in evaluateMathExpression()
with a recursive descent parser that safely evaluates basic arithmetic
expressions.
The Function constructor is a security anti-pattern that could enable
arbitrary code execution if the validation regex is ever bypassed or
relaxed. The new parser:
- Only supports numbers, +, -, *, /, parentheses, and whitespace
- Has no eval-like functionality that could execute arbitrary code
- Maintains backward compatibility with existing expressions
- Handles operator precedence and parentheses correctly
Fixes#725
* Apply suggestion from @coderabbitai[bot]

Fix for #703.
Adds an optional sampleRate parameter to the decodeAudioToFloat32() function. The caption transcriber passes in a value of 16000 to prepare audio in the format Whisper expects.
Major features and improvements:
* **Clip Effects**:
* Added UI in Properties Panel to manage effects on video/image clips (add, remove, toggle, reorder).
* Implemented dynamic parameter fields for effects.
* Added support for keyframing effect parameters.
* **Assets Panel**:
* Added sorting options: Name, Type, Duration, and File Size.
* Persisted view preferences (grid/list mode, sort order) to local storage.
* Refactored media item rendering and drag interactions.
* **Timeline & Interaction**:
* **Keyframe Dragging**: Added ability to drag keyframes directly on the timeline element.
* **Resizing**: Improved resize logic to respect neighboring clips (prevents overlaps).
* **Visuals**: Implemented tiled background rendering for video/image clips on the timeline.
* **Shortcuts**: Added "Deselect All" action bound to the `Escape` key.
* **Fixes**: Corrected drag-and-drop coordinate calculations when the timeline track area is scrolled.
* **Text Elements**:
* Refactored text background storage to use an explicit `enabled` flag.
* Added `V8toV9` storage migration to update existing projects.
* **Architecture**:
* Moved export state management to `ProjectManager` for better lifecycle handling.
* Refactored `PropertiesPanel` sections to be more composable (custom headers, borders).
