Ophir LOJKINE e07594579b Refactor SQL parameter handling into unified expression tree
Replace the `StmtParam`/`ParameterExtractor` machinery with a shared
`SqlPageExpr` type parameterized over its input source, distinguishing
standalone expressions from per-row expressions via the type system.

Rename `ParsedSqlFile` to `SqlFile` and split SQL parsing into dedicated
`dialect`, `rewrite`, and `statement` submodules. Queries are now
rewritten into either a database query with bindings and computed
columns, or a single-row query evaluated without a database round trip.

Make `SqlPageFunctionName` parsing case-insensitive and support
SQLPage-computed projections and nested functions over query results.
