NEW FireBAT: Map -> Print Advisory

**As a** *FBAN/FBS* **I want** *to save the FBA as a PDF* **So That** *the RWCO can review and sign it and it can be distributed to dispatchers, Ops, Plans, IMT colleagues, and stakeholders (sometimes industry/contractors in the field) as appropriate.*

**Additional Context**
- see [Figma](https://www.figma.com/file/AUhBnTB50dnY7ysoxBSqPN/FireBAT-2021?node-id=207%3A2) - needs heavy design collaboration
- There is an area for capturing text relating to the FBA - this may imply we are dealing with two screens - screen 1) capture information and screen 2) display advisory preview / print.
- There may be future requirements around who has rights to view and edit the FBA.
- There are concerns around the rendered FBA changing on the fly - which would cause it to differ from the final PDF.
- Think in terms of 3 separate screens. Screen 1: Edit, Screen 2: Read only, Screen 3: System dialog print preview
- Screen 2 and Screen 3 are really the same page, but in print mode, the styles are slightly different. Screen 2 is rendered with CSS making it a normal web page. Screen 3 is rendered with CSS that renders it appropriately for printing.

**Acceptance Criteria**
- [ ] Given I am on the "Preview FBA" screen, When I look at the screen, What I see is as close as possible to what is going to end up being printed to PDF.
- [ ] Given I have clicked on the "Print / save as PDF" button, I can use the system dialog to print/save the page as show in the system dialog preview.
- [ ] Given I have printed/saved the output, it is formatted correctly for Portrait.

**Definition of Done**
- [ ] Ready to Demo in Sprint Review
- [ ] Does what I have made have appropriate test coverage?
- [ ] Documentation and/or scientific documentation exists and can be found
- [ ] Peer Reviewed by 2 people on the team
- [ ] Manual testing of all PRs in Dev and Prod
- [ ] Merged

Start with the linked Figma design and clarify the proposed edit, read-only preview, and print-preview screens with the team. No files, tests, or entry points are named in the issue, so first locate the existing FBA/map interface and its frontend tests. Done means the preview matches the PDF closely and portrait printing or saving works through the system dialog.
