* fix: the query being updated after deleting the variables

* fix: use exact variable string match when removing clauses on delete

Passing `true` to removeKeysFromExpression removed the first clause whose
value contained any `$`, which corrupted expressions when two variables
shared the same filter attribute (e.g. $env and $env_region both backed
by deployment.environment). Switching to the exact variable string
(`$${variableName}`) ensures only the deleted variable's clause is removed.

Also adds 9 targeted edge-case tests covering shared-key variables,
variable-name boundary ($env vs $environment), mixed literal/variable
clauses, multi-value array filter items, clickhouse_sql, idempotency,
empty widgets, and unrelated-variable no-ops.

* fix: refined the deletiong process

* fix: adding toast

* fix: resolved comments

* fix: updated the tests and moved func to utils
