The previous approach deleted migration records to force re-application,
but this is dangerous for migration 2 which DELETEs all categories and
keywords before re-inserting them, wiping user customizations.
Now computes the expected SHA-384 checksum (matching sqlx) and updates
the stored checksum in _sqlx_migrations, so the migration is recognized
as already applied without being re-run.

Add repair_migrations Tauri command that deletes stale migration 1
checksum from _sqlx_migrations before Database.load(). Migration 1
is idempotent (CREATE IF NOT EXISTS) so re-applying is safe.
Fixes "migration 1 was previously applied but has been modified".

Each profile gets its own SQLite database file for complete data isolation.
Profile selection screen at launch, sidebar switcher for quick switching,
and optional 4-6 digit PIN for privacy. Existing database becomes the
default profile with seamless upgrade.

Add export (JSON/CSV) and import (full replace) to the Settings page.
Export supports 3 modes (transactions+categories, transactions only,
categories only) with optional password encryption using Argon2id key
derivation. Import detects encrypted .sref files, prompts for password,
and shows a destructive confirmation modal before replacing data.
