Function normalize_channel

nodedb/src/control/notify_bus.rs:244–246

Normalize a channel name to lowercase, matching PG unquoted-identifier rules. Quoted identifiers preserve case; unquoted identifiers are folded to lowercase. We receive them already stripped of quotes from the SQL layer, so we just lowercase everything that wasn't explicitly quoted.

pub fn normalize_channel(channel: &str) -> String {
    channel.to_lowercase()
