feat: accept ND_-prefixed env var names in config files (#5258)

* feat: add toPascalCase helper for config key display

Adds a toPascalCase helper that converts dotted lowercase Viper config keys
(e.g. 'scanner.schedule') to PascalCase (e.g. 'Scanner.Schedule') for use
in user-facing warning messages. Includes export_test.go binding and a
full Ginkgo DescribeTable test suite covering simple, dotted, multi-segment,
already-capitalized, and empty-string cases.

* feat: remap ND_-prefixed env var names found in config files

Detect when users mistakenly use environment variable names (like
ND_ADDRESS) in config files, remap them to canonical keys, and warn.
Fatal error if both ND_ and canonical versions of the same key exist.

Closes #5242
