chore: Add resource schema hooks and fix ip access list semantics

[laylaazouz]

Description

• Converts ip_access_list on mongodbatlas_mcp_config and
  mongodbatlas_project_mcp_config (and their data sources) from a list to
  a set
• adds resource schema hooks to make it behave correctly against
  the Atlas API.

🤖 Augment PR Summary

Summary: This PR aligns MCP configuration IP access-list handling with the API's unordered semantics.

Changes:

• Converts MCP configuration IP access lists from nested lists to nested sets in resources and data sources.
• Regenerates schemas, models, and documentation to expose the attributes as sets.
• Adds resource schema hooks requiring exactly one of ip_address or cidr_block per entry.
• Adds a set plan modifier so API-recreated computed entry fields are replanned as unknown on updates.
• Normalizes echoed IPv4 host CIDRs out of PATCH request bodies.
• Updates acceptance assertions to test unordered nested-set entries, including a multi-entry project case.
• Moves project-scoped MCP tests to execution-created projects and makes org cleanup tolerate already-deleted configurations.

Technical Notes: The set conversion addresses unstable API ordering and avoids inconsistent-result errors after multi-entry updates.

At internal/serviceapi/mcpconfig/resource_custom_hooks.go:64, this only recognizes an echoed IPv4 host CIDR (/32), but ip_address also supports IPv6, whose equivalent echoed CIDR is /128. A subsequent update of an IPv6-backed configuration can therefore submit both fields, which the API rejects as mutually exclusive.

Severity: medium
