feat: add Amazon Connect resources

[chrisns]

Summary

• Add 12 new Amazon Connect resource types covering instances and all major sub-resources: ContactFlow, ContactFlowModule, Queue, RoutingProfile, User, SecurityProfile, PhoneNumber, HoursOfOperation, QuickConnect, Rule, and IntegrationAssociation
• Addresses [resource] amazon connect #343 — Connect had zero coverage; orphaned instances with per-minute pricing and phone numbers (~$1/day each) accumulate cost
• All resources use AWS SDK v2 with paginators, NewPropertiesFromStruct, and tag fetching via ListTagsForResource

Resource details

Resource	Filter	Notes
ConnectInstance	Skip CREATION_IN_PROGRESS/CREATION_FAILED	DependsOn all 11 sub-resources
ConnectContactFlow	Only CONTACT_FLOW and CAMPAIGN types	System-managed flows are filtered
ConnectContactFlowModule	—	—
ConnectQueue	Skip AGENT type	Auto-created, undeletable
ConnectRoutingProfile	Skip "Basic Routing Profile"	Disassociates queues before delete; DependsOn ConnectUser
ConnectUser	—	—
ConnectSecurityProfile	Skip Admin, Agent, CallCenterManager, QualityAnalyst	Built-in profiles
ConnectPhoneNumber	—	Uses ReleasePhoneNumber API
ConnectHoursOfOperation	Skip "Basic Hours"	Default hours
ConnectQuickConnect	—	—
ConnectRule	—	—
ConnectIntegrationAssociation	—	No tags (no suitable ARN)

Design decisions

• Shared listConnectInstances() helper in connect-common.go used by all sub-resource listers
• Deletion order enforced via DependsOn: Users → RoutingProfiles → other sub-resources → Instance
• ConnectAgentStatus intentionally omitted (no delete API exists)
