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).
