Timeline: group same-date/actor events, clean badges, Bedrock routing

- renderTimeline(): group consecutive same-date+actor events into one card
  with a bullet list; single events keep their current layout
- Date format: YYYY-MM-DD → "1 Jun 2023" (3-letter month, international)
- Time shown in header when available
- Remove date_type badge; confidence badge replaced by amber ⚠ flag on
  low-confidence events only (high/medium border colour still shows)
- LegalTools.php: resolve azure_full/azure_mini to Bedrock Sonnet/Haiku
  when DbnBedrockGateway is active; claude_sonnet/claude_haiku also handled
- timeline.php + api/timeline.php: engine labels updated (Claude Haiku/Sonnet);
  claude_haiku + claude_sonnet added to valid engine list
- i18n engine labels updated in all 4 languages
