refactor: update installer generator templates to instance-based API

Update generator templates to produce installers following the new pattern:

Actions template (objname_actions.vtemplate):
- Convert all functions to methods on the config struct
- startupcmd() -> (self &Struct) startupcmd()
- running() -> (self &Struct) running_check()
- start_pre/post, stop_pre/post -> methods on struct
- installed(), install(), build(), destroy() -> methods on struct
- Add InstallArgs struct with reset parameter
- Remove get()! calls, use self instead

Factory template (objname_factory_.vtemplate):
- Update play() to get name parameter for all actions
- Call instance methods instead of module-level functions
- Add support for start_pre, start_post, stop_pre, stop_post actions
- Update start(), stop(), running() to use self.method() calls
- Remove duplicate InstallArgs and wrapper methods
- Use self.running_check() instead of running()

All newly generated installers will now follow the consistent
instance-based pattern with proper lifecycle hook support.
