Fix crash in Migration 48 due to missing transfer columns

Description

This PR fixes a crash that occurred during the database migration from version 47 to 48.
The application was throwing an IllegalStateException: Migration didn't properly handle: transfers because the transfers table schema in the database did not match the OCTransferEntity definition.

Specifically, the following columns were missing in the migration but expected by the Entity:

• tusUploadUrl
• tusUploadLength
• tusUploadMetadata
• tusUploadChecksum
• tusResumableVersion
• tusUploadExpires
• tusUploadConcat

Changes

• Migration_48.kt: Added the missing ALTER TABLE statements to add the TUS-related columns to the transfers table.
• MigrationToDB48Test.kt: Added a new instrumentation test to verify that the migration from version 47 to 48 completes successfully and that the new columns are correctly added while preserving existing data.

Verification

• Created and ran MigrationToDB48Test.
• Verified that the test passes on API 36 emulator.
