feat: Update nutrition metrics and energy balance calculations

- Introduced a single TDEE calculation based on current weight, replacing the fixed 2500 kcal value.
- Updated `get_energy_balance_data` to use daily totals for intake calculations and improved energy balance logic.
- Enhanced `get_nutrition_average_data` to calculate averages over calendar days instead of raw log entries.
- Adjusted placeholder resolution to ensure consistent metadata usage across requests.
- Fixed issues in the charts router to reflect the new energy balance logic and TDEE calculations.

These changes improve the accuracy of nutritional assessments and streamline data handling in the application.

 - In der automatischen Zusammenfassung in der Endnode kommt als Überschrift, z.B. Node 10, anstatt den Node-Name auszugeben. 
 - Alle Änderungen an Nodes scheinen automatisch in den Gesamtflow übernommen zu werden. Diese werden dann nach dem Speichern aktiv. Da muss man sehr vorsichtig sein, bei kurzen Änderungen und dem Ausprobieren.
 - Der Testlauf "Execute" sollte auf dem aktuellen Workflowstand ausgeführt werden, auch wenn dieser vom gespeicherten Abweicht. Ich würde natürlich vor dem Speichern den Workflow testen können. Prüfe und bewerte diesen Punkt, setze ihn aber noch nicht um. 
-- Die Workflows werden aktuell nicht in Analyse und den verfügbaren KI-Asuwertungen angezeigt. ggf. weil wir sie aktuell noch keinem Bereich zuordnen können. Diesen könnten wir ggf. über die Start-Node im Workflow konfigurieren. 
 - Das löschen von Knoten und Kanten funktioniert aktuell nur über Backspace nicht über entfernen
 - Wir sollten auch dafür sorgen, dass jeweils nur eine Start-Node, End-Node in einem Workflow existiert, Prüfe ob mehrere End-Nodes sinnvoll sind, da wir ja auch Logik-Pfade abbilden und ggf. auch eine route beschreiten, die ein anderes Ende hat. (Prüfe, ob das heute schon möglich wäre!)
 - Als zukünftige Ausbaustufe sollten wir überlegen, ob wir auch Trigger implementieren, z.B. um Kurzstatements zu generieren, wenn neue Daten hereinkommen und wir diese Bewertungen aktualisieren wollen

+- **`main.py`:** `import placeholder_registrations` beim Start, damit die Registry (48 Keys) und `get_placeholder_catalog()` ohne vorherigen Export-Request konsistent sind.
+- **`placeholder_resolver.py`:** `{{top_goal_progress_pct}}` nutzt `_safe_int` statt `_safe_str` (Verdrahtung zu `scores.get_top_priority_goal` korrigiert).
+
+### Updates (11.04.2026 - Ernährung: eine TDEE-/Tageslogik)
+
+- **`data_layer/nutrition_metrics.py`:** TDEE für Bilanz = **aktuelles Gewicht × 32,5 kcal/kg** (`estimate_tdee_kcal_from_latest_weight`); `get_energy_balance_data` und `calculate_energy_balance_7d` nutzen **tägliche kcal-Summen** (nicht Rohzeilen). Makro-Durchschnitte über **Tagesmittel**; `protein_adequacy_28d`, `macro_consistency_score`, `get_protein_adequacy_data`, `get_macro_consistency_data` auf **Kalendertag** umgestellt. Entfernt: festes **2500 kcal** in `get_energy_balance_data`.
