Nikhil Mantri ad68a1b991 refactor: extract shared list filter SQL compiler from the dashboards visitor (#12806) ...

#### Description

- Extracts the dashboards list filter visitor's generic core into a
shared package, `pkg/parser/filterquery/sqlcompiler`: boolean
composition, operator dispatch, value extraction, the LIKE family
builders and the `Compiled` output type, behind a small per-feature
`FieldResolver`.
- Dashboards keeps only a key-policy resolver (`listfilter_resolver.go`)
and an error-code wrap; the old 631-line visitor is deleted. Emitted SQL
is unchanged, pinned by the existing exact-SQL unit suite.
- Scope note in the package doc: this compiler serves list pages over
the relational sql DB. Telemetry queries stay on querybuilder's
ClickHouse visitor.
- Also fixes a pre-existing bug shared with the copy: a `LIKE`/`ILIKE`
pattern ending in an unescaped backslash never matches on sqlite and
aborts the query on Postgres (a data-dependent 500); it is now rejected
as a 400, with a unit case.
- Split out of #12780 per review so the commoning-out merges first; the
alert rules list API consumes this next (#12780 will be rebased onto
this branch). Part of SigNoz/pulse-pod#226.
