Add manual 'Save result' to all tools — replaces auto-save

All tool results can now be saved to My Case manually. Users click
'Save result', type a description, and confirm. This replaces the
previous silent auto-save on barnevernet/timeline/etc., giving users
control over what stays and what it's called (supports multiple runs
of the same tool with different titles).

- CaseResults: extend ELIGIBLE_TOOLS to include summarize, ask, redact,
  transcribe; add toolLabel/toolIcon entries; support explicit title
  via meta['title'] in save()
- api/case/save-result.php: new client-initiated save endpoint;
  accepts tool + title + input_payload + output_payload + meta
- Remove CaseResults::save() auto-save from barnevernet, deep-research,
  discrepancy, korrespond, timeline API endpoints
- tools.js: add showSaveResultButton() (exposed as window.dbnShowSaveResultButton);
  wire for ask, redact, timeline, transcribe (both file-upload and
  stored-audio paths)
- barnevernet.js: wire save button after final result render
- summarize.js: wire save button after renderFinal(); passes sumResults
  container so widget appears in the correct #sumResults div
- case-result.php: rich tool-specific rendering for summarize, ask,
  redact, transcribe, timeline; update re-run link map to include all
  new tools
- tools.css: styles for .save-result-widget and its states (idle,
  prompt, done, error)
