feat(filters): add Date & Point “is” for private and public query

[0xTaneja]

Added Date and Point is value filters to both private and public queries.

fixes #440

Changes Made :-

for private query,
In types.ts, I extended EntityFieldFilter<T> to support Date and ReadonlyArray<number>.
Another change which i made was in ,
findMany.ts , evaluated Date via getTime() and Point via [x, y] deep equality.

for public query from what i understood from the codebase was that useQueryPublic already passes $filter and selects time/point, so no extra wiring needed.

edited translate-filter-to-graphql.ts -
Date → time: { is: Graph.serializeDate(date) }
Point → point: { is: Graph.serializePoint([x, y]) }

Added a few tests on public & private queries
No breaking changes. Only adds filter capabilities.
Applies only when users provide Date/Point filters.
