Add docs for complex features.

Remove unnecessary dependencies inside app module build.gradle.kts.

Following security crypto deprecation, the dependency io.github.osipxd:security-crypto-datastore should be replaced with io.github.osipxd:encrypted-datastore. (library dependency)

Project's Github workflow called linting-on-pr.yml has detekt checks, which should run only if the number of .kt/.kts files is above zero.

Due to the deprecation of Accompanist placeholder owing to its lack of maintenance, the recommended approach is to duplicate the source code. However, a challenge arises as the current method for creating custom modifiers has shifted from composed {} to Modifier.Node. Consequently, a new implementation must be devised from the existing one, while retaining the basic, fade, and shimmer effects.

Currently, when opening a new PR, a detekt linter is run on all project files, which adds time to the PR. Ideally, detekt checks should be applied to changed files only.

To make the detekt config more usable, it should be moved out of the app module to the base directory.

The detekt.yml has a reference to formatting, but detektPlugins("io.gitlab.arturbosch.detekt:detekt-formatting:$version") is missing.

Before merging pull requests, ensure that linting and formatting checks are passing. Set up a process that requires these actions and rejects the PR if they are not completed successfully.

DataStore is the modern recommended data storage solution to store key-value pairs/typed objects. However, it currently lacks native encryption/decryption capabilities. On the other hand, EncryptedSharedPreferences has been available for some time.

Several approaches exist to implement encryption:

• use EncryptedSharedPreferences, sacrificing the advantages offered by DataStore (not really ideal)
• create an EncryptedSerializer using Keystore (complicated to deal with)
• use encrypted-datastore as an interim solution until an official resolution is provided (check that it doesn't use EncryptedSharedPreferences under the hood)
