Code improvements, remove redundant files, update compose-ui in sample apps

[kiftio]

What are you trying to accomplish?

Updates, many of which were IDE/linter recommended:

• rename database to db in the migrate() calls, as db is used in the signature of the method we're overriding
• remove lint baseline, as it's no longer needed
• use entries instead of values() in enums
• Remove unused color resource (white) and drawables
• Rename webview to WebView, and min to minutes in test names to fix reported typos
• Use data object over object in our sealed classes
• update compose-ui in the sample app

Entries vs Values - https://kotlinlang.org/docs/enum-classes.html#working-with-enum-constants

Prior to the introduction of entries in Kotlin 1.9.0, the values() function was used to retrieve an array of enum constants.

Data Objects - https://kotlinlang.org/docs/object-declarations.html#data-objects

Data object declarations are particularly useful for sealed hierarchies like [sealed classes or sealed interfaces](https://kotlinlang.org/docs/sealed-classes.html), since they allow you to maintain symmetry with any data classes you may have defined alongside the object.
