CAMEL-23618: camel-tui - Add payload size metrics to Endpoints tab

[davsclaus]

Summary

• Display body and header size columns in the Endpoints table when message size tracking is enabled
• Add mirrored sparkline chart showing IN vs OUT average body sizes over time (yellow/magenta)
• Add "Reset Stats" action to F2 menu that resets route counters, endpoint registry stats, and all local sparkline history
• Rename consumer TOTAL column to POLLS to clarify it tracks scheduler poll count
• Reset endpoint registry on reset-stats action in LocalCliConnector

Test plan

• Build the TUI plugin module with mvn install
• Run with a Camel integration that has messageSizeEnabled=true
• Verify BODY and HDR columns appear in Endpoints tab when size data is available
• Verify payload size sparkline renders alongside the message rate sparkline
• Verify F2 → Reset Stats clears all sparkline graphs across Overview and Endpoints tabs
• Verify consumer tab shows POLLS column header instead of TOTAL

Adds payload size metrics (mean body size) tracking to the TUI Endpoints tab with sparkline history, plus a new "Reset Stats" action in the Actions menu. The reset logic properly clears both the server-side stats (via reset-stats action file) and all local sparkline history maps. RuntimeEndpointRegistry.reset() is also called in LocalCliConnector.doActionResetStatsTask().

Large diff (~800 lines), but mostly TUI rendering and history bookkeeping following the established pattern for other metric types (throughput, remote endpoints). Reviewed source code, config, and TUI integration — generated metadata skimmed.

LGTM.
