Fix dashboard point displays to honor decimal precision settings

[ccpk1]

Summary

Fix dashboard point displays so they honor the decimal precision preference across the remaining user, admin, and classic templates.

Standards reference

• Canonical authoring/process standards: Dashboard Template Guide

Change type

• Template update/fix
• New dashboard template

Template submission checklist

If this PR adds a new dashboard template, confirm all required assets are included:

• Added a new versioned template file in templates/
• Added/updated matching dashboard_registry.json entry
• Added/updated matching preference documentation in preferences/
• Verified source.path and preferences.doc_asset_path values are correct

Required development standards

• Uses dynamic, integration-instance-aware lookup patterns for helper/sensor references
• Does not manually construct or hardcode entity IDs
• Follows replacement field patterns without custom token formats
• Uses ui.get() translation lookups for all user-facing strings, and format fallback as err-<key> for easy troubleshooting. i.e. ui.get('done', 'err-done')
• Reused existing translation keys where possible; added missing keys to translations/en_dashboard.json when required.
• Handles missing required entities gracefully with fallback messaging and skip-render guard behavior
