refactor(resources): one canonical layout, scoped bases, dedup schemas

[Datata1]

Implements plans/refactor/04-resource-layer-normalization.md:

• Canonical per-resource layout everywhere: operations.py / schemas.py / resources.py. Renamed domain+usage manager.py and envVars/git/ landscape/logs models.py to resources.py; git schema.py -> schemas.py; deleted the zero-byte landscape/resources.py placeholder
• envVars/ package renamed to env_vars/; the old camelCase import path remains as a deprecation shim module (warns, re-exports)
• Domain entity moves to domain/schemas.py alongside its base (matching Team/Workspace); TeamDomainManager lives in domain/resources.py; domain/init.py gains proper re-exports
• New TeamScopedResource / WorkspaceScopedResource bases in core/base.py replace six copy-pasted manager __init__s; managers expose team_id/workspace_id consistently
• EnvVar derives from CamelModel like every other schema (gains to_dict/to_json/to_yaml)
• PipelineStatusList is now an alias of ResourceList[PipelineStatus] instead of a reimplementation
• PaginatedResponse: refresh() hoisted from the two response subclasses, limit/offset are non-Optional with defaults (drops the repeated 'or 25' re-defaulting); single _clamp_page_size helper replaces four inline min(max(...)) clamps
• Deleted dead utils.dict_to_model_list

Only internal module paths moved; all public re-exports (top-level codesphere, package __init__s) are unchanged, plus the envVars shim.
