- CrossHubPropagation: IHP.Prelude.head returns Maybe a; use List.head
(Data.List.head, already imported qualified) for non-empty-guarded lists
- Sessions: currentUserOrNothing is pure Maybe, not IO; use case...of instead of >>=

- Sessions: replace raw authenticate/unsetSession with IHP login/logout/verifyPassword
- Widgets/New, Widgets/Show: consolidate imports to Web.View.Prelude
- Widgets/Show: unwrap Id newtype for childrenOf comparison, Double → Scientific in renderSignalValue

Convert all remaining `<- paramOrNothing / param / paramOrDefault /
currentUserOrNothing` monadic binds to `let` — these functions are pure
(ImplicitParams-based) in IHP v1.5, so `<-` is a type error in an IO
do-block.
Controllers fixed:
AgentDelegations, AiGovernancePolicies, Annotations, ApiConsumers,
CollectiveProposals, DecisionRecords, DeploymentRecords,
HubCapabilityManifests, HubRoutingRules, InstitutionalKnowledge,
OutcomeCorrelations, RequirementCandidates, TypeRegistries,
WebhookSubscriptions, Widgets,
Api/V2/{Annotations,InteractionEvents,Token}
WebhookSubscriptions: remove orphaned `Right () ->` case arm that was
left inside a bare `unless` block (structural parse error).
Also carries forward all in-progress fixes from the working tree:
helpers (AgentBridge, ApiRateLimit, BottleneckDetector,
CrossHubPropagation, FrictionScore),
views (CanSelect instances, HSX lambda extraction, formFor wrappers),
env/build (envrc GHCi perms, flake.nix Tailwind + GHC resource limits,
static/app.css additional Tailwind output).
