DatabaseProvisionerInstrumentedTest crashed in @Before setUp() on API 31/32 with ArrayIndexOutOfBoundsException (length=0; index=0), passing on API 29. The stack shows the throw is entirely in the test harness: mockk<Context>() -> MockK JvmMockFactoryHelper.isKotlinInline -> kotlin-reflect ReflectJavaMember.getValueParameters, which indexes parameterAnnotations[0] on an empty array. Mocking android.content.Context makes MockK walk the whole framework class with kotlin-reflect, and on Android 12/12L ART returns a parameter-annotation array shorter than the parameter-type array for some Context method, so kotlin-reflect throws. Production DatabaseProvisioner/DatabaseEncryption code never runs. Replace the mockk<Context> with a real ContextWrapper(appContext) that overrides getDatabasePath to route the cache file to the test DB and delegates everything else, sidestepping the framework-class reflection walk. Verified 3/3 pass on the dev36 GMD emulator; API 31/32 left to CI (images not installed locally).

PR #234 (issue #232, merged into this branch) bumped the Room schema 18->19 and made the MessageDao search queries match Unicode-casefolded *Fold columns. Two lane-3 tests were stale against it:
- DatabaseEncryptionTest.schemaVersionIsCarriedOntoTheEncryptedFile hardcoded the pre-#234 schema version 18; bump to 19 (matches LibreMailDatabase version = 19).
- MessageDaoTest's search-summary tests inserted MessageEntity fixtures without populating the new senderFold/senderEmailFold/subjectFold/snippetFold columns, so the casefolded LIKE matched nothing ([]). Populate them in the message() helper via lowercase(), mirroring production (Mappers.toEntity + MessageDao.updateHeaderContent/updateBody).
MigrationTest already covers 18->19 (migrate18To19_addsAndBackfillsCasefoldSearchColumns plus the auto-discovered full-chain replays), so no change there. Verified: targeted connectedDebugAndroidTest of MessageDaoTest+DatabaseEncryptionTest+MigrationTest on the API 36 emulator = 32 tests, 0 failures.

Instrumented (androidTest) coverage for data/local: Room DAO queries/mutations,
every exported-schema migration, and DatabaseProvisioner/DatabaseEncryption
(SQLCipher) provisioning branches, incl. a regression guard for the SQLCipher
System.loadLibrary cold-start crash (592a797).
Validated locally: 114/181 instrumented tests passed, 0 failed, via
connectedDebugAndroidTest on a manually-provisioned api36 emulator. The local
GMD emulator wedges mid-suite (~112) on this machine (see #269); CI validates
the full 181 on its own runners.
Closes#248
