fix(provider): resolve unknown values after apply for all resources

Fix 'Provider produced inconsistent result after apply' and 'unknown
values after apply' errors across all 19 resources. Fixes #53.

Code fixes:
- Unwrap nested API responses (key/info, team/team_info, etc.)
- Change IsNull() else-clause zeroing to IsUnknown() checks
- Only set API-injected defaults when user originally configured them
- Remove server-side runtime fields from resource schemas
- Add UseStateForUnknown plan modifiers for stable computed fields
- Fix organization update to use PATCH instead of POST
- Fix guardrail litellm_params to only store user-configured keys
- Fix search_tool to parse search_tool_info JSON before sending
- Expand mcp_server auth_type validator to include all API values

Documentation:
- Rewrite all 18 resource docs to match actual Go schemas
- Rewrite all 21 data source docs to match actual Go schemas
- Fix examples with outdated attribute names and values
- Remove YAML frontmatter, standardize code block language to hcl

Testing:
- All 12 unit tests pass
- All 19 resources verified via live integration testing
