v0.1.0-dev09

[[FEAT] Added Details in Viewer

• For now, the details only display some common ones, but in the future, more items will be added using MediaMetaDataRetriever and ExifInterface.

[FEAT] Added Header composable that displays list headers. This simplifies the process of displaying headers in lists, etc.
[FEAT] The app now uses DefaultFontFamily instead of a GoogleFont.
[FIX] Fixed issue with TwoPane causing details not to occupy space as intended.
[FEAT] Added VideoIntent for handling video file clicks temporarily. Future updates will include a built-in video player.
[FEAT] Added Modifier.thnIf with lambda Modifier scoped. This makes adding conditional modifiers simple.
[REFACTOR] Added SCR_Z_INDEX to each sharedElement; this ensures that zIndex is preserved between screens properly.
