fix+ux(settings): clearer provider/model flow, inline provider editing

- Merge Anbieter and Standard-LLM-Parameter into one card with explicit
  step labels (Schritt 1: Anbieter, Schritt 2: Modell setzen)
- Show current default provider name in step 2 so it's always visible
- Add inline edit form per provider row (pencil button toggles form)
- Add /providers/{id}/update and /providers/{id}/clear-key routes
- Fix sqlite3.Row.get() AttributeError in _prompt_llm_block and
  _process_analysis_job (use .keys() instead)
