Add custom icon fonts to lvgl-module (#499)

* **New Features**
  * Added Material Design symbol fonts and LVGL font aliases for launcher, status bar, and shared UI icons.

* **Style**
  * Migrated app icons across the UI to the new symbol font system.
  * Updated launcher button sizing, font styling, recoloring and icon text color for consistency.
  * Default text/icon font macros set for consistent sizing across the UI.

* **Documentation**
  * Updated third‑party notices to include Material Design Icons links.
