Added Quest Mii management features

- Introduced new layout files for Mii items, Mii editor, and My Miis page.
- Implemented MiiData serialization and deserialization tests to ensure data integrity.
- Created MiiDatabase tests to validate database creation, modification, and error handling.
- Added MiiIds tests to verify ID generation and MAC address derivation.
- Developed MiiRenderer tests to confirm rendering functionality for Mii parts.

+**My Miis**, after Patches, is the PC's MiiListPage with its Mii editor
+(`MiisPage`, `MiiEditor`). It lists and changes the Wii's Mii database in the
+game's own NAND, `shared2/menu/FaceLib/RFL_DB.dat` (`MiiDatabase`, the PC's
+`MiiRepositoryService` and `MiiDbService`), which the game reads, so a Mii made here
+can be picked for a new licence. The Quest's NAND starts without one, so the page
+creates it empty the first time, as the PC does, with one difference: a database
+the Wii formatted links its 10,000 hidden-Mii entries to nothing (`0x7FFF`), and
+the PC leaves those links zero, so the headset writes the Wii's (checked byte for
+byte against Dolphin's database). A Mii is the 74-byte block of the PC's
+`MiiSerializer` (`MiiData`). A Mii made or duplicated here gets a new ID and this
+console's system ID, from the MAC address the runtime derives from `setting.txt`'s
+serial (`RuntimeConsoleIdentity::FromSerial`), so making one needs the game to have
+started once. An imported `.mii` gets the PC's import address and, like any Mii
+from another console, the PC's globe. The PC selects more Miis with Shift or Ctrl;
+here a long press adds or removes one. Export saves one `.mii` through the save
+dialog, several into a chosen folder. Changes are refused while the game runs.

+The pictures come from a Kotlin port of the PC's software renderer (`MiiRenderer`,
+`FflResource`), without the PC's body, whose 3DS models are not ours to ship, so
+the head is drawn alone, as the Wii's own Mii icons show it. It draws from FFL's
+Mii parts (`FFLResHigh.dat`), which are Nintendo's and never in the APK: like the
+PC, the page downloads them once from the Internet Archive's copy of Miitomo's
+`AFLResHigh_2_3.dat` (a 4.4 MB zip) and checks them against their SHA-256
+(`MiiRenderResource`). Compared with the PC's C# renderer on 257 Miis covering
+every part and colour, 283 of 299 pictures were identical and the rest differed by
+one colour level in at most four pixels, except for one deliberate fix: the PC
+colours a beard with the hair colour, here with the facial hair colour, as the Wii
+does. The editor's choices are drawn from the same parts, the flat parts from their
+textures in the Mii's colours and hairstyles, head shapes and beards as the Mii's
+head, where the PC shows icons of its own. On a Quest 3 the 424-pixel face in the
+editor takes about 150 ms, drawn in four bands of rows in parallel, and a choice
+about 40 ms. `MiiDataTest`, `MiiDatabaseTest`, `MiiIdsTest` and `MiiRendererTest`
+(on a made-up parts file) cover it.
