fix(discover): cast nullable params so Postgres can infer type

Browse Source 
The discover @Query used the `(:param is null or col >= :param)` idiom.
For the timestamp (publishedAfter) and numeric (minRatio) params, Postgres
threw "could not determine data type of parameter $1" because the bare
`$1 is null` placeholder is untyped — returning HTTP 500 and breaking the
whole /discover page. (The search() query survives because its nullable
params are only bigint/varchar, which Postgres can null-type.) Wrap the
two problematic params in cast(... as timestamp/big_decimal) in the
is-null check so the type is explicit. ORDER BY ... nulls last / fetch
first were never the problem.
