docs: address review feedback from PR #1857

Fix conversion artifacts, typos, grammar errors, and technical
inaccuracies flagged by automated code review (Copilot + CodeRabbit).

Infrastructure: add root-level md-*.md exclusion to conf.py,
fix sphinx-autobuild ignore globs in Makefile.

Content: fix curly quotes, invalid Go panic() calls, shell quoting
in cURL examples, incorrect firewall command paths, typos across
22 documentation files, remove duplicate sections.

 VPP Dataplane in VyOS supports sFlow for traffic monitoring and analysis.
 
-The VPP Dataplane integration works hand-in-hand with normal kernel sFlow agent, which is responsible for collecting and exporting sFlow samples. VPP itself is responsible for generating the samples.

-To enable sFlow in VPP, you first need to configure the service using the same steps as for normal kernel sFlow agent, as described in {doc}`/configuration/system/sflow`. Then you can enable sFlow on VPP interfaces.

-sFlow collects statistics only for traffic *received* on the interface. If you want to monitor traffic *sent* on the interface, you need to enable sFlow on the corresponding interface in the opposite direction.
