Add required Maven Central POM metadata

[AhmedNMahran]

Summary

This adds the Maven Central POM metadata currently required by Central validation for all published artifacts.

What changed

• added shared project metadata entries in gradle/libs.versions.toml for:
  • license
  • SCM connections
  • developer identity
• updated all published modules to include the missing POM sections:
  • licenses
  • developers
  • scm

Updated modules:

• auth
• mutations-definitions
• persistence
• syncengine
• sync-pipelines (mobile-sync)
• umbrella

Why

Central validation reported the following metadata warnings/errors during publish:

• License information is missing
• SCM URL is not defined
• Developers information is missing

These fields are required for Maven Central publication and need to be present on every published artifact.

Validation

Regenerated publication POMs successfully with:

./gradlew \
  :sync-pipelines:generatePomFileForKotlinMultiplatformPublication \
  :auth:generatePomFileForKotlinMultiplatformPublication \
  :persistence:generatePomFileForKotlinMultiplatformPublication \
  :syncengine:generatePomFileForKotlinMultiplatformPublication \
  :mutations-definitions:generatePomFileForKotlinMultiplatformPublication \
  --no-configuration-cache \
  --stacktrace

Verified generated POMs now include:

• <licenses>
• <developers>
• <scm>

Note

The POM metadata now uses org-safe developer information:

• id = quran
• name = Quran Foundation

No personal email is included in the published metadata.

The license metadata is set to GPL-3.0 to match quran_android.

If mobile-sync is intended to use a different license, that should be corrected before the first successful Central release so the published metadata matches the actual project licensing.
