feat(template): add opportunity_score to country-overview — stats strip, landscape, top-opp cities, FAQ

Both DE + EN language variants. All additions wrapped in {% if avg_opportunity_score %}
guards for graceful degradation.

Changes per language:
- Stats strip: avg Opportunity Score as 5th item (with auto-fit CSS now supporting this)
- Market Landscape section: paragraph on opportunity interplay (high opp + low market =
  first-mover signal; high both = proven demand + open sites)
- New section: "Top Locations by Investment Potential" — table of top_opportunity_names
  (distinct from top Market Score cities)
- New FAQ: explains Market Score vs Opportunity Score difference (avg values used)

DE copy written with linguistic mediation — native investor register, Du-form.

+
+Der **Market Score (Ø {{ avg_market_score }}/100)** bewertet die Marktreife: Bevölkerungsgröße, bestehende Anlagendichte und Datenqualität. Der **Opportunity Score (Ø {{ avg_opportunity_score }}/100)** dreht die Logik um: Er misst Investitionspotenzial — Versorgungslücken, Einzugsgebiet und Tennisinfrastruktur als Proxy für Racket-Sport-Affinität. Für Standortentscheidungen ist die Kombination beider Scores am aussagekräftigsten: Hoher Opportunity Score bei niedrigem Market Score signalisiert White-Space-Chancen. Hoher Wert in beiden zeigt Märkte, in denen Nachfrage belegt ist und trotzdem noch offene Standorte existieren.

+
+The **Market Score (avg. {{ avg_market_score }}/100)** measures market maturity: population size, existing venue density, and data quality. The **Opportunity Score (avg. {{ avg_opportunity_score }}/100)** inverts that logic: it scores investment potential based on supply gaps, catchment reach, and tennis infrastructure as a proxy for racket sport demand. For site selection, the combination of both scores is the most informative signal. A high Opportunity Score with a low Market Score points to white-space locations. High on both means proven demand with open sites still available.
