pgwatch sets lock_timeout to 100ms during metric collection, which causes the monitoring to report 100ms instead of the actual configured value. This fix queries reset_val from pg_settings for lock_timeout to get the genuine configuration value. Closes #61

Bug: is_default inconsistent with lock_timeout value
For lock_timeout, tag_setting_value now comes from reset_val while is_default is still derived from source (the session-overridden value). When pgwatch sets lock_timeout during collection, source becomes session, causing is_default to report non-default even if the configured reset_val equals the default, making the emitted fields contradictory.

Report the actual lock_timeout by using reset_val in the settings metric and add unit/integration tests to verify it.
