This commit introduces a convention plugin for multiplatform projects to centralize common configuration.

The plugin sets up the JVM toolchain, configures JVM and JS targets, and adds basic dependencies for common, JVM, and JS source sets.

Individual module build scripts now use the `kotlinMultiplatformConvention` plugin to apply this shared configuration.

This commit introduces a TOML catalog for managing dependencies and plugins, replacing inline version definitions.
It updates build scripts across the project to utilize the catalog, promoting consistency and simplifying dependency management.
Additionally, it configures repositories for plugin and dependency resolution in the settings file.

Updated code snippets to utilize the TOML catalog for managing dependencies and Java language version.
This removes redundant version definitions and promotes consistency across the project.

This commit updates the Gradle wrapper to version 8.10.2 and replaces jcenter with mavenCentral as a repository. It also removes dependencies from the `deps` version catalog and updates some existing dependencies to point to `libs` instead.
