Log Message:

Switch dwtool log-scan and esn-trace from CloudWatch to Loki

Logs now go directly to Grafana Cloud Loki via Fluent Bit, so dwtool needs to query Loki instead of CloudWatch. Adds a Loki HTTP client that queries /loki/api/v1/query_range with LogQL, and rewrites both log-scan and esn-trace to use it.

Credentials are loaded from ~/.config/dwtool/config.json (with DWTOOL_LOKI_HOST/USER/PASSWORD env var overrides). The Loki client strips Fluent Bit key_value wrapper and log4perl timestamp/level prefix from messages so output is clean.

Other fixes: - Renamed logscan → log-scan for consistency with esn-trace - Fixed flag parsing in esn-trace: Go's flag package stops at the first positional arg, so esn-trace URL -since 24h silently ignored -since. Args are now reordered so flags come first. - log-scan uses -service instead of -groups for filtering by Loki service label instead of CloudWatch log group glob - Service column is hidden when -service is specified (redundant)

Log Message:

remove cloudwatch agent sidecar from web task definitions

The CW agent was configured to collect Apache access logs but was pointing at a -DISABLED log path, so it was burning resources for nothing. Removes the sidecar container, log-share volume, and associated mount from all four web service task definitions.
