fix: centralize plugin defaults for settings UI

[chubes4]

Summary

• centralize plugin defaults for max_turns and Action Scheduler queue tuning in PluginSettings
• expose backend defaults through the settings ability so the admin UI stops hardcoding fallback values
• update chat, pipeline, and settings UI code to use the centralized defaults, including the intentional default of max_turns = 25

Notes

• changelog intentionally untouched
• validation on this VPS was noisy due to local env issues (missing JS deps / flaky extension env), so this PR is mainly to capture the clean follow-up change for review
