feat(delightful-dashboards): Show results directly on dashboard

[tutntut]

Problem

• The results page only shows Response ID + timestamp, which are not meaningful for processing. Admins — especially school admins — cannot tell who or what a submission is about without clicking into every response or exporting a CSV. This is repeatedly cited as the reason the results dashboard is not usable for day-to-day ops.
• No quick way to search or filter for specific submissions — admins fall back to exporting CSVs multiple times and filtering in Excel/Google Sheets
• Our usefulness score for dashboard is at 2.4/5 (below hygiene of 4.2/5)

Solution

• Team PRD
• AI-agent PRD

Behind the delightful-dashboard flag, the Responses tab renders a new UnlockedResponsesV2 that decrypts responses client-side and surfaces their field values directly as table columns (alongside submission-meta columns), instead of only Response ID + timestamp (and workflow details). Rows stay clickable to open the full individual response. Client-side decryption is gated behind a 1,000-response cap per date range; over-cap, the container shows a "narrow the range" prompt before any decryption runs. The date range is sourced from StorageResponsesContext so the picker, the decrypt query key, and the cap gate all agree on one range.

Alternatives considered

• We considered keeping the hackathon table's isResponseLimitExceeded prop for port-fidelity, but the over-cap state now lives in the container (before decryption, mirroring ChartsPage), so the table would never see it — dead surface that invites a divergent second over-cap UI later.
• We considered keeping V2's own local useState date range from the hackathon, but develop already owns dateRange in StorageResponsesContext (shared with the download and count queries); a second source of truth would let the cap gate and the decrypt disagree.

Screenshots

Breaking Changes

No - backwards compatible; new behaviour is behind the delightful-dashboard feature flag (off by default).

Tests

TC1: Field values render as columns

• Enable the delightful-dashboard flag; open a storage-mode form's Results → Responses and enter the secret key
• Field answers (incl. Checkbox/Table) render as columns alongside Response ID + timestamp

TC2: Click into an individual response

• Click a row; it opens that submission's individual response view with all fields (no regression)

TC3 (MRF): workflow columns

• Open an MRF form's dashboard → Workflow status, Pending response at, and Reminders columns render (before the field columns)

TC4: Search by response ID

• Search a response ID → the table narrows to the matching row and the count shows the result count
