[PR#895] feat: add support for M6 tool change policy

_

Extract the M6 tool change handling logic into a separate method to avoid code
duplication and improve maintainability, since the same logic is repeated in
multiple places.

[src/server/controllers/Grbl/GrblController.js [241-251]](https://github.com/cncjs/cncjs/pull/895/files#diff-4dacbcae20bbf70f0461da55cad9e5a4315835c0150c2f99d6f99bf626afa28aR241-R251)

-const toolChangeAction = config.get('state.controller.toolChange.action', TOOLCHANGEACTION_PAUSE);
-if (toolChangeAction === TOOLCHANGEACTION_PASSTHROUGH) {
-  // Passthrough
-} else if (toolChangeAction === TOOLCHANGEACTION_IGNORE) {
-  // Ignore
-  line = line.replace('M6', '(M6)');
-} else {
-  // Pause (default)
-  this.feeder.hold({ data: 'M6', msg: originalLine }); // Hold reason
-  line = line.replace('M6', '(M6)');
-}
+line = this.handleM6ToolChange(line, originalLine);

Move the radio button options into a configuration array to make the code more
maintainable and reduce repetition.
