feat: parse env var strings to expected config value types (#3107)

* fix: add try_parse_bool for env var strings to enable config overrides of boolean values

* fix: fallback to given value if not parseable

* feat: extend eval to all valid types

* fix: remove return type

* fix: prevent strange type conversions by providing expected type

* feat: add tests
