fix: resolve all GHC 9.10.3 / IHP 1.5 compile errors (all 616 modules load)

Fix 13 modules that blocked compilation on Alpine:

- FrontController: remove annotationLauncherScript helper (IHP Html is a
  constrained type synonym); add (?context, ?request) constraint to
  defaultLayout matching what setLayout expects
- HubCapabilityManifests: switch JSONB fill to paramList+toJSON; fix dynamic
  SQL Text→Query via fromString/cs; void sqlExec; add Control.Monad.void
- Hubs: replace raw Array sqlQuery with filterWhereIn query builder;
  fix isInList validators
- DecisionRecords: remove unregistered DistilDecisionAction; fix hub
  resolution chain via candidateId→sourceWidgetId; BridgeResponse(..)
- RequirementCandidates: BridgeResponse(..); remove @Widget type apps from
  fetchOneOrNothing; void ConfidenceAnnotation createRecord
- AdaptiveThresholds: fix sqlQuery tuple param (Only hubId)
- AgentDelegations, AgentRegistrations, Widgets: BridgeResponse(..)
- Annotations, DeploymentRecords, GovernanceTemplates: minor type fixes
- DecisionRecords/Edit view: extract formAction before HSX block
