Feat: Make helm flags timeout and force configurable

[tobbber]

Closes #647

[Copilot]

Pull request overview

This PR adds configuration knobs for Helm’s --timeout and --force behavior, exposing them via global HelmConfig (and timeout additionally at the individual HelmApp level) and updating docs/schemas/tests accordingly.

Changes:

• Add timeout (global + per-HelmApp) and force_replace (global) to Helm configuration/models.
• Wire timeout precedence (local → global → default) into Helm flag construction and add tests for precedence.
• Regenerate/update JSON schemas, env var docs, and CLI init snapshot to reflect the new config fields.

• helm_config.force_replace is currently added to the shared helm_flags, which are reused for template_flags. This means --force will also be passed to helm template when force_replace is enabled, even though --force is an upgrade/install concern and can break templating/manifest generation. Consider explicitly disabling force for HelmTemplateFlags so helm template stays unaffected by this setting.

    @property
    def template_flags(self) -> HelmTemplateFlags:
        """Return flags for Helm template command."""
        return HelmTemplateFlags(
            **self.helm_flags.model_dump(),
            api_version=get_config().helm_config.api_version,
        )
