feat: extract and display event times on timeline (kl. HH:MM etc.)

Prompt now instructs the model to extract time of day (HH:MM) when
present in Norwegian formats: kl. 14:30, kl 09.00, 14:30, 14.30.
renderTimeline shows time as a muted inline annotation next to the date.
CSV export gains a Time column after Date.

+IMPORTANT — Norwegian date and time formats to recognise:
 - DD.MM.YY  (e.g. 18.09.25 = 2025-09-18, 09.04.25 = 2025-04-09)
 - D.M.YY    (e.g. 6.1.25 = 2025-01-06)
 - DD.MM.    (e.g. 18.09. — day and month without year; infer year from surrounding context)
 - D.M.      (e.g. 6.1. — day and month only)
 - DD.MM.YYYY (e.g. 18.09.2025)
 - Two-digit years: always interpret as 20YY (25 → 2025, 24 → 2024).
+- Times: "kl. 14:30", "kl 09.00", "14:30", "14.30" → extract as "14:30" (HH:MM 24-hour).
 - Diary / log format: lines that begin with a date followed by a colon or space are ALWAYS events.
   Example: "18.09.25: Samtale med Davids lærer" → date 2025-09-18, event "Samtale med Davids lærer".
   Example: "6.1. Samtaler med David"             → date unknown-year-01-06, event "Samtaler med David".
+  Example: "18.09.25 kl. 09.00: Møte på skolen" → date 2025-09-18, time "09:00", event "Møte på skolen".
 - Do NOT skip a line just because the year is ambiguous — record what you can and set confidence accordingly.
 
 For each temporal reference provide:
 - "date": ISO 8601 date (YYYY-MM-DD) if determinable, otherwise a human-readable description such as "06 Jan (year unknown)"
+- "time": time of day in HH:MM (24-hour) if present in the source text, otherwise null
 - "date_type": one of  absolute | relative | recurring | conditional | period
 - "actor": person, institution, or party involved — or "unknown"
 - "event": concise description of what happened or is due
