fix: Correctly validate relationship enum values in eq, neq and in methods

[kamilogorek]

Builds on top of #588

I couldn't find a nice way to remove duplication from ResolveFilterValue calls, and we need to branch out there, as ResolveFilterValue is sometimes wrapped in NonNullable, sometimes in ReadonlyArray and sometimes in nothing. Fallback values are also different.

In perfect world this would work, but I don't know hot to express a type for Wrapper as a generic accepting a single type 🤔

type ResolveFilterValue<
  Tables extends Record<string, GenericTable>,
  Row extends Record<string, unknown>,
  ColumnName extends string,
  Wrapper,
  Fallback
> = ColumnName extends `${infer RelationshipTable}.${infer RelationshipColumn}`
  ? ResolveFilterRelationshipValue<Tables, RelationshipTable, RelationshipColumn>
  : ColumnName extends keyof Row
  ? Wrapper extends Something
    ? Wrapper<Row[ColumnName]>
    : Row[ColumnName]
  : Fallback

Fixes #169
Fixes #351

I guess?™️
