Time & date, system events and much more (#152)

## Time & Date - Added time to statusbar widget - Added Time & Date Settings app - Added TimeZone app for selecting TimeZone - Added `tt::time` namespace with timezone code ## Other changes - Added `SystemEvent` to publish/subscribe to system wide (e.g. for init code, but also for time settings changes) - Changed the way the statusbar widget works: now there's only 1 that gets shown/hidden, instead of 1 instance per app instance. - Moved `lowercase()` function to new namespace: `tt::string` - Increased T-Deck flash & PSRAM SPI frequencies to 120 MHz (from 80 MHz) - Temporary work-around (+ TODO item) for LVGL stack size (issue with WiFi app) - Suppress T-Deck keystroke debugging to debug level (privacy issue) - Improved SDL dependency wiring in various `CMakeLists.txt` - `Loader` service had some variables renamed to the newer C++ style (from previous C style)
