Walkthrough

Replaces in-repo JaCoCo SBT plugins with the external MoranaApps jacoco-method-filter plugin, updates build/plugin config and CI report path, and adds trailing newlines across many Scala source files (formatting-only).

Changes

Cohort / File(s)	Summary
Trailing newline formatting balta/src/main/scala/za/co/absa/db/balta/DBTestSuite.scala, balta/src/main/scala/za/co/absa/db/balta/classes/*, balta/src/main/scala/za/co/absa/db/balta/implicits/*, balta/src/main/scala/za/co/absa/db/balta/postgres/*, balta/src/main/scala/za/co/absa/db/balta/typeclasses/*, balta/src/main/scala/za/co/absa/db/mag/*	Added trailing newlines / blank line at EOF across many Scala files; purely formatting, no logic or public API changes.
Removed in-repo JaCoCo plugins project/FilteredJacocoAgentPlugin.scala, project/JacocoBaseKeysPlugin.scala	Deleted two custom SBT plugins and their public autoImport keys/tasks/helpers/commands that implemented JaCoCo integration and optional JMF-based rewriting.
Build config and plugins update build.sbt, project/plugins.sbt	Switched project to .enablePlugins(JacocoFilterPlugin) in build.sbt and added addSbtPlugin("io.github.moranaapps" % "jacoco-method-filter-sbt" % "2.0.1") to project/plugins.sbt.
CI workflow update .github/workflows/jacoco_report.yml	Adjusted Jacoco report path used by GitHub Action from balta/target/**/jacoco/report/jacoco.xml to balta/target/**/jacoco-report/jacoco.xml to match new plugin output location.

Poem

🐇 I hopped through lines both short and neat,
Swapped plugin shoes and fixed the beat.
New filter hums while reports align,
Files got newlines — tidy by design.
A carrot clap for builds divine! 🥕

In `@project/plugins.sbt`:
- Around line 2-3: The plugin artifact declared with addSbtPlugin uses a
non-existent ID ("io.github.moranaapps" % "jacoco-method-filter-sbt" % "2.0.0");
change the artifactId to the correct one that includes the Scala/Scala-compiler
suffix (e.g., "jacoco-method-filter-sbt_2.12_1.0") so the addSbtPlugin call
references "io.github.moranaapps" % "jacoco-method-filter-sbt_2.12_1.0" %
"2.0.0" (or the appropriate Scala suffix for your build) to match Maven Central.
