feat(import): parse otpauth URIs and unencrypted Aegis JSON in resumable steps

Streaming JSON tokenizer with depth and length limits and native skipping
of long strings; Aegis reader for database versions 1-3 with groups and
encrypted-export detection; otpauth parser with ';' separators and Steam;
import job with Replace mode, duplicate and replacement checks, a sealed
multi-part buffer and a report. Google Authenticator exports deferred.
