Improve SDK and SWQOS logging: alignment, errors, duration format

- Rename wait_transaction_confirmed to wait_tx_confirmed (params, lib, docs, examples)
- SDK timing: use [SDK][provider] style with fixed-width labels; add newline before block
- Move print_sdk_timing_block to common::sdk_log; unify SWQOS_LABEL_WIDTH
- SWQOS submitted/failed: aligned [Provider] labels via log_swqos_submitted/submission_failed
- Extract short error message from JSON (message/data) or quoted string; prefix with 'error: '
- Format elapsed as 'X.XXXX ms' or 'X.XXXX µs' (4 decimals, space before unit); use comma before error
- Add SwqosType::as_str() for zero-allocation log labels; only parse JSON when input starts with '{'
