♻️ Convert Local module to KMP #535

Convert the local module to KMP. In order to do that, we need to migrate from Room to SQLDelight.

A new `shared` module was create to hold all the shared logic between the different mobile platforms. Future changes will make the `shared` module the new `domain` if possible. Since the `:domain` module is already Kotlin-only, the code was simply moved and works!

Moved the dependencies from the Kotlin-only to the Kotlin Multiplatform Mobile one

For some reason, Kotlin-only modules do not find the KMM modules. This module was temporarily converted to Android to make the code work. In the future, this module will also be a KMM one.

Small back-and-forth to convert the `shared` to the old `domain`. Now that everything is set, the module was updated to the original name.

Oopsy, I removed the tests when moving the class between the modules. The classes are now back and removed the junit dependencies since it doesn't work well with KMM.

Removing Java's Calendar and adapting the logging tool to its multiplatform version. Some work was needed for the convertions since the Android layers will keep using Calendar for now. Future commits will address the TODOs and make it more clear.

Fix the logging system in the remaining use cases and also some oopsies along the way.

All the domain tests are working fine again all the Calendar/DateTime migration

A few lint complaints

Instrumented tests fixed

When renaming the module from "shared" to "domain", one property was missed. Updated!

When migrating to KMM, the checkers were removed from the Gradle script. The quality plugin was re-added and the lint fixes updated.

Now that everything is set on the correct KMM directory, no need to keep this folder anymore.

When running the Android Test task, KMP requires the minimum SDK to 30 to allow space in the test names. Another solution is to remove the spaces and use simple names. The following regex was used to make the job easier: \s+(?=(?:(?:[^`]*`){2})*[^`]*`[^`]*$)

The Instant API requires min SDK 26, so we can't use the emulator on 24 anymore

Previously, some versions were inside the Version Catalog TOML and others were in the AlkaaVersions file. Since the versioning and compiling will be even more important now that we will compile with KMP, all the versions are centralized in a single place. Also, the VersionCatalogExtensions was broken in several classes to make it easier to understand. They are: Bundles, Libraries and Versions.

Convert the Domain module to a KMP module

During the file moving, instead of creating "com/escodro/domain", I created "com.escodro/domain". Now everything is fine again.

🚚 Organize the domain folders

The Repository module was migrated from Android/Kotlin-only module to KMP. For now, we are not caring too much about ProGuard, so the files were removed.

For consistency, the class directory was named to "kotlin"

Since one more layer was converted from java.Calendar to kotlinx.DateTime, now the local layer will be responsible for the mapping.

Room was removed to make space for the new-shiny-multiplatform SQLDelight.

Replacing Room with SQLDelight was _delightful_.

A single unit test was updated

Following the KMP module structure, the files were moved accordingly. Also some minor import changes required regarding the Dispatchers.
