Fix incorrect block logging for FAWE replaceBlocks (#624)

[TWME-TW]

Summary

Fixes #624 — When using //replace with FAWE, CoreProtect was logging block changes
for every block in the selected region, including blocks that did not match the mask
(e.g. air blocks being logged as having stone placed in them).

Root Cause

replaceBlocks(Region, Mask, Pattern) called processPatternToBlocks without
passing the Mask parameter:

// Before (incorrect)
processPatternToBlocks(world, region, pattern); // mask ignored
return eventExtent.replaceBlocks(region, mask, pattern);

This caused processPatternToBlocks to iterate over every position in the region
and log a block change regardless of whether that position matched the mask.
Meanwhile, eventExtent.replaceBlocks correctly applied the mask, so the actual
world changes were accurate — only the CoreProtect log was wrong.

Fix

Added a processPatternToBlocks(World, Region, Mask, Pattern) overload that skips
positions where mask.test(position) returns false, and updated replaceBlocks
to use it:

// After (correct)
processPatternToBlocks(world, region, mask, pattern);
return eventExtent.replaceBlocks(region, mask, pattern);

Changes

CoreProtectLogger.java

• Updated replaceBlocks to pass mask to processPatternToBlocks
• Added processPatternToBlocks(World, Region, Mask, Pattern) private overload
  with a mask.test(position) guard to skip non-matching blocks
