New themes (#677)

- Implemented themes with LSS: material, material mono
- Implemented grid-based navigation
- Added new Launcher
- Updated Appearance app to add theme configuration
- Updated various apps to improve UX/UI
- Added LVGL widgets: cards, badges, chips, icon buttons
- Added support for round/rounded displays
- Added the concept of insets to LVGL and implemented it in toolbar + statusbar
- Terminal app now hides toolbar by default, but tapping the terminal toggles visibility
- File browsing now opens the configured user-data location by default
- Added missing licenses to subprojects
- Updated README.md screenshots and intro text

+Derivative Works; within the Source form or documentation, if provided along
+with the Derivative Works; or, within a display generated by the Derivative
+Works, if and wherever such third-party notices normally appear. The contents of
+the NOTICE file are for informational purposes only and do not modify the
+License. You may add Your own attribution notices within Derivative Works that
+You distribute, alongside or as an addendum to the NOTICE text from the Work,

+#### 8. Limitation of Liability
+
+In no event and under no legal theory, whether in tort (including negligence),
+contract, or otherwise, unless required by applicable law (such as deliberate
+and grossly negligent acts) or agreed to in writing, shall any Contributor be
+liable to You for damages, including any direct, indirect, special, incidental,

+# ADS1115 ADC
+
+A driver for the Texas Instruments `ADS1115` 16-bit I2C ADC, exposed as an ADC controller
+with the four single-ended inputs AIN0 to AIN3 as channels 0 to 3.
+
+Each read is a single-shot conversion. The result is returned as a 12-bit value: 0 to 4095
+covers 0 V to the configured full-scale voltage, negative readings are returned as 0.
+Written from the TI datasheet (SBAS444).

+# ES7243E microphone ADC
+
+A driver for the `ES7243E` stereo audio ADC by Everest Semiconductor, wired as an
+input-only `AUDIO_CODEC_TYPE` device. The I2C bus is the device's parent, the I2S
+controller carrying the audio data is referenced via a devicetree phandle. The ADC
+runs as I2S slave with MCLK from the pad (MCLK = 256 x sample rate).
+
+Wraps Espressif's `esp_codec_dev` ES7243E implementation.
