Tag keys and tag-value placeholders use different syntax, which could lead to malformed configurations.

For example, a user could enter [zip_code] as the tag key when the correct key is zip_code.

Bracket syntax is still valid when a tag is referenced as a value or placeholder.

Brackets are automatically removed when entered around a tag key—for example, [zip_code] becomes zip_code.

Selecting a tag for the key field inserts the plain tag name.

Selecting a tag for the value field continues to insert the bracketed placeholder.

The same tag-key normalization applies when mapping RTB response values to tags.

Updated helper text makes the difference between key and value syntax clearer.

Call Flow and RTB tag mappings are less likely to be saved with malformed tag keys.

Existing placeholder behavior for tag values remains intact.
