fix(datable): ignore non-hash bounds instead of raising

[jplot]

Summary

A declared datable attribute given a scalar or array value — e.g. ?filters[value_date]=2026-01-01 straight from a query string — raised TypeError when the date filters read bounds[:after] on a String, violating the gem's never-raise contract.

Changes

• Datable.columns now drops attributes whose value is not a hash of bounds, so a malformed shape narrows nothing (single guard shared by the four date filters)
• specs: scalar and array values, plain hash and ActionController::Parameters, no longer raise and return the untouched relation

Pull request overview

This PR hardens the Filterable::Datable date filters so malformed filters shapes (e.g., a scalar/array where a bounds hash is expected) are ignored rather than raising, preserving the gem’s “never-raise” contract when consuming raw query-string params.

Changes:

• Add a single guard in Filterable::Datable.columns to drop non-Hash bounds before the four date filters read bounds[:...].
• Extend specs to cover scalar/array malformed bounds for both plain hashes and ActionController::Parameters, asserting no exception and an unchanged relation.

File	Description
spec/filterable_spec.rb	Adds regression coverage ensuring malformed date-filter shapes don’t raise and don’t narrow results.
lib/filterable/datable.rb	Filters out non-hash bounds in Datable.columns to prevent TypeError from bounds[:key] on scalars/arrays.
