fix(config): trim whitespace from relay-owner-nsec CLI/env input

When relay_owner_nsec is provided via CLI argument or environment
variable (e.g., read from a file by the NixOS module), trim any
leading/trailing whitespace including newlines. This matches the
behavior when reading from the .relay-owner.nsec file directly.

Fixes issue where NixOS module reads nsec file with 'cat', which
includes the trailing newline, making the nsec invalid when passed
as a CLI argument.

Also reverted the tr workaround in nix/module.nix since ngit-grasp
now handles this correctly.
