The Legacy API message lookup endpoints parsed the request body as JSON and passed the `id` parameter straight through to the message database. A JSON object supplied for `id` arrived as a Ruby Hash and was used as a raw set of SQL `WHERE` conditions. `hash_to_sql` interpolated each Hash key directly inside backtick identifier quoting while escaping only the value, so a key containing a backtick could break out of the identifier and inject arbitrary SQL into the SELECT (blind, time-based) against the message database. Fixes: - Escape all identifiers (columns, tables, database names) through a new `escape_identifier` helper that wraps in backticks and doubles embedded backticks. Applied across hash_to_sql, select, insert, insert_multi, update and delete so no caller can inject via an identifier. - Validate the Legacy API `id` parameter at the controller boundary: reject any non-scalar value before it reaches the database and coerce it to an integer. Internal Hash-based lookups (e.g. tracking middleware) are unaffected. Adds regression tests at the unit (hash_to_sql / escape_identifier) and request (legacy messages/deliveries) levels.
