fix: report file name mapping interpolation failures

[efegokdemir]

Summary

• Report file-name mapping interpolation failures through the Maven plugin logger.
• Wire the execution context to the owning Mojo logger so failures are no longer silently swallowed.

Changes

• Preserve existing module behavior while emitting a warning with the original exception when mapping evaluation fails.
• Keep the logger optional for direct/unit use of module classes.

Testing

• mvn -Dspotless.skip=true -DskipITs -Dinvoker.skip=true test — passed (48 tests)
• git diff --check — passed
• mvn -DskipITs -Dinvoker.skip=true test — blocked by the local Palantir Java formatter/JDK incompatibility (NoSuchFieldError for JCTree$JCCompilationUnit.endPositions).

Fixes #515
