fix(cli): strip {{enums}} placeholder in legacy CommandBox generator template

The legacy CommandBox-module generator (cli/src/models/TemplateService.cfc)
substituted {{belongsToRelationships}}, {{hasManyRelationships}},
{{hasOneRelationships}}, and {{validations}} but had no branch for the
{{enums}} placeholder carried by its model template. box wheels generate
model therefore leaked a literal {{enums}} into the generated config() body
as invalid CFML. This legacy path has no enum codegen (unlike the LuCLI
generator at cli/lucli/services/CodeGen.cfc), so the placeholder is now
stripped unconditionally, mirroring the no-validations fallback.

Adds a regression spec under cli/lucli/tests/specs/services/ that exercises
the legacy TemplateService.processTemplate via makePublic and asserts the
{{enums}} placeholder never survives into generated output.

+- CLI: the legacy CommandBox-module generator (`cli/src/models/TemplateService.cfc`) substituted `{{belongsToRelationships}}`, `{{hasManyRelationships}}`, `{{hasOneRelationships}}`, and `{{validations}}` but had no branch for the `{{enums}}` placeholder that ships in its model template, so `box wheels generate model` leaked a literal `{{enums}}` into the generated `config()` body as invalid CFML. This legacy path has no enum codegen (unlike the LuCLI generator), so the placeholder is now stripped unconditionally, matching the no-validations fallback (#3180)
