feat: support utopia-php/storage 3.0

[loks0n]

Summary

Adopts utopia-php/storage 3.0.0. Three changes:

• getType() now returns the DeviceType enum, so the JSON and CSV sources compare against DeviceType::Local instead of the removed Storage::DEVICE_LOCAL constant.
• setTransferChunkSize() was removed upstream in favour of a per-call argument: the JSON and CSV destinations pass Transfer::STORAGE_MAX_CHUNK_SIZE to transfer() directly.
• composer.json requires utopia-php/storage: 3.* and php: >=8.5 (storage 3.0's floor — a version bump signal for maintainers: this likely warrants a minor at least).

Why

This release unblocks the Appwrite migration to storage 3.0 (appwrite/appwrite#12921), which is currently draft because this package pins storage 2.*.

Testing

• composer lint (pint) passes
• composer check (PHPStan level 3, src + tests) passes — it caught the two setTransferChunkSize() calls a plain grep missed
• Unit suite: 62 tests / 380 assertions pass against storage 3.0.0, including the JSON/CSV export tests that exercise the Local device transfer path

Greptile Summary

This PR updates the migration library for storage 3.0. The main changes are:

• PHP and utopia-php/storage requirements are raised.
• CSV and JSON sources compare device types with the new enum.
• CSV and JSON destinations pass the transfer chunk size per call.
• The lockfile is refreshed for the new dependency set.

Confidence Score: 5/5

This looks safe to merge.

• No blocking issues found in the changed code.
• The API updates match the storage 3.0 migration described by the dependency change.
• The CSV and JSON source and destination changes stay mirrored.
