fix(chart): render webapp/electric extras when provided as a templated string

Guard the new extraInitContainers/extraContainers (webapp) and
extraVolumes/extraVolumeMounts (electric) consumers with a kindIs "string"
check. When the value is a structured list it still renders via
tpl (toYaml .) $ as before; when it is a YAML block-scalar string
(as the GovSignals umbrella chart feeds it, with embedded {{ include }}
helpers) it is rendered via tpl . $ directly, avoiding the stray "|"
block indicator that toYaml emits for strings and breaks list parsing.
Backward-compatible: list values render identically.
