feat(migration): add project-level resource migrations

[premtsd-code]

Adds support for migrating project-level Appwrite resources end-to-end.

Greptile Summary

This PR adds end-to-end migration support for five new project-level Appwrite resources: auth methods, security policies, protocols, service flags, and RBAC labels. It also bumps the SDK from v23 to v24 to access the Project service APIs required by the new resource types.

• Source: Adds exportAuthMethods, exportPolicies, exportProtocols, exportLabels, and exportServices to Sources/Appwrite.php, each wiring up singleton-count reporting and correct (int) $e->getCode() ?: Exception::CODE_INTERNAL error handling. Also backfills the same error-code fix for the existing project-variable and webhook handlers.
• Destination: Adds createAuthMethods, createPolicies, createProtocols, createLabels, and createServices to Destinations/Appwrite.php. Auth methods and policies use hardcoded storage-key strings (documented intentional divergence from SDK enum values) and share a read-modify-write on the auths attribute; protocols and services use SDK enum values as map keys against their respective apis/services attributes. Renames the $project string field to $projectId throughout to avoid collision with the new Project service instance.
• New resource classes: Five clean singleton data classes (AuthMethods, Policies, Protocols, Labels, Services) are added with matching fromArray/jsonSerialize/getters.

Confidence Score: 5/5

Safe to merge; the new export and import paths are isolated singleton handlers with no mutation of shared state beyond the expected project document fields.

The destination writes use careful read-modify-write patterns with purgeCachedDocument after each update, auth methods and policies write disjoint key sets into the shared auths attribute, and the error-code cast fix was correctly backfilled. The main concerns are efficiency rather than correctness.

src/Migration/Sources/Appwrite.php — the new export helpers each fetch the project document independently; worth consolidating in a follow-up.

Important Files Changed

Filename	Overview
src/Migration/Sources/Appwrite.php	Adds exportAuthMethods, exportPolicies, exportProtocols, exportLabels, exportServices; fixes existing error-code cast for project-variable and webhook handlers; project->get() is invoked up to four separate times and getPolicy() nine times during export
src/Migration/Destinations/Appwrite.php	Adds createProtocols, createLabels, createServices (direct DB write via dbForPlatform, read-modify-write on apis/services attributes) and createAuthMethods, createPolicies (read-modify-write on the shared auths attribute); renames $project → $projectId; all use correct SDK enum keys except auth methods which intentionally use hardcoded storage keys
src/Migration/Resources/Auth/AuthMethods.php	New singleton resource for auth-method flags (7 bool fields); clean fromArray/jsonSerialize/getters
src/Migration/Resources/Auth/Policies.php	New singleton resource for 13 security-policy fields; clean construction and serialization
src/Migration/Resources/Settings/Services.php	New singleton resource for 17 per-service enable/disable flags; straightforward data class
src/Migration/Resources/Settings/Protocols.php	New singleton resource for REST/GraphQL/WebSocket protocol flags; straightforward data class
src/Migration/Resources/Settings/Labels.php	New singleton resource carrying the project's RBAC label array; straightforward data class
src/Migration/Resource.php	Adds TYPE_AUTH_METHODS, TYPE_POLICIES, TYPE_PROTOCOLS, TYPE_LABELS, TYPE_SERVICES constants and registers them in the supported-types list
src/Migration/Transfer.php	Adds new types to GROUP_AUTH_RESOURCES, GROUP_SETTINGS_RESOURCES, and the all-resources array; changes are additive and correctly grouped
composer.json	Bumps appwrite/appwrite SDK dependency from 23.* to 24.* to access new Project service APIs
