feat(migration): replace sqlx::migrate with standalone Go migrate tool

Schema is now managed by a separate Go CLI at tools/migrate/, which embeds the SQL files copied from server/initialize/migrate/database/ and tracks state in the shared schema_migrations table. Rust no longer owns migrations at startup. Rust startup: 1. Connect to DB 2. Probe for the `user` table (schema marker) 3. If missing, fork-exec `ppanel-migrate up` to bring schema to v2131 4. Create admin if not present 5. Continue with redis/queue/scheduler Verified: - Empty DB → ppanel-migrate applies all 39 migrations in ~0.4s, admin created - Go server's ppanel_go DB → schema detected, migrate skipped, clean start Changes: - Add tools/migrate/ — Go module wrapping golang-migrate * migrate/migrate.go: Migrate() + RunUp() (RunUp bypasses the iofs vs os.ErrNotExist sentinel mismatch that breaks Up() on already-migrated DBs) * migrate/sql/{postgres,mysql}/: SQL files copied from server * cmd/migrate/main.go: CLI (up/down/version/force/drop) - Widen password column from varchar(100) → varchar(255) in 00001_init_schema.up.sql to fit Rust's 112-char PBKDF2 hash (Rust uses 16-byte salt; Go's 8-byte salt fits in 100 but Rust's doesn't) - Rewrite src/migration.rs: * Remove sqlx::migrate!, run_migrations() * Add ensure_schema(db, cfg): probe + invoke ppanel-migrate subprocess - Fix src/db.rs::build_dsn: previously used cfg.config verbatim even when the default config string was for the wrong dialect (PG got MySQL's charset=utf8mb4 string and crashed on connect) - Delete old migrations/{postgres,mysql}/ (no longer used) Co-Authored-By: Claude <noreply@anthropic.com>
