feat(seedless-onboarding): add dataType support for secret data items

[huggingbot]

Explanation

The metadata service now supports a dataType column for categorizing secret data (PrimarySrp, ImportedSrp, ImportedPrivateKey). This enables clients to distinguish between different types of backed-up secrets

Changes include:

• Add dataType parameter to insert operations
• Add updateSecretDataItem and batchUpdateSecretDataItems for updating existing items
• Update fetchAllSecretData to return storage metadata (itemId, dataType) alongside secret data
• Refactor SecretMetadata to separate local metadata from storage-level metadata

Checklist

• I've updated the test suite for new or updated code as appropriate
• I've updated documentation (JSDoc, Markdown, etc.) for new or updated code as appropriate
• I've communicated my changes to consumers by updating changelogs for packages I've changed
• I've introduced breaking changes in this PR and have prepared draft pull requests for clients and consumer packages to resolve them

Note

Adds first-class support for dataType (PrimarySrp, ImportedSrp, ImportedPrivateKey) and migrates legacy secrets to the new format.

• Controller: addNewSecretData now requires dataType: EncAccountDataType (BREAKING); SecretType is derived internally. New runMigrations and setMigrationVersion; persists migrationVersion and handles legacy items via updateSecretDataItem/batchUpdateSecretDataItems.
• SecretMetadata: Adds storage-level fields (itemId, dataType, createdAt, storageVersion); new compare, compareByTimestamp, and matchesType; fromRawMetadata now requires storage metadata; removes parseSecretsFromMetadataStore, fromBatch, and sort (BREAKING).
• Sorting/validation: Fixes TIMEUUID ordering via timestamp extraction; fetchAllSecretData returns storage metadata, sorts with PrimarySrp first, and validates primary SRP type.
• Utils/exports: Adds getTimestampFromTimeuuid, compareTimeuuid, getSecretTypeFromDataType; re-exports EncAccountDataType.
• Minor: bump @metamask/utils to ^11.9.0.

May I know are there any major difference between #storageVersion and #version?
If not we can remove either one of them.

removed version entirely and kept storageVersion here. This should work for old clients too because we're not using version in our logic at all

[huggingbot]

do we need to also update SocialBackupsMetadata?

[huggingbot]

Should we move this logic to SecretMetadata class? wdyt?

fixed here

Misclicked.
