feat(dashboard): add Rison-encoded URL filter support

Adds ?f=(...) URL parameter support for hydrating dashboard filters from
human-readable Rison syntax. Matches URL filters to native filters by column
name (case-insensitive, handles spaces) and auto-applies them by populating
both filterState.value and extraFormData. Unmatched filters render as
removable chips in a "URL Filters" section above cross-filters.
