The forward_failed error log only included account_id, making it
difficult to identify which account and proxy caused the failure
without querying the database. Add account_name, account_platform,
and proxy details (id, name, host, port) to the log fields.

LegacyPrintf uses inferStdLogLevel() to infer log level from message
text. Any message containing the word "error" is classified as ERROR
level, causing the entire signature-retry recovery flow (which succeeds)
to produce spurious ERROR log entries.
Changes:
- Remove noisy [SignatureCheck] debug logs inside isThinkingBlockSignatureError
that were logging every detected signature check as ERROR
- Change retry-start log to WARN level via [warn] prefix
- Change retry-success log to INFO level by removing "error" from message
