Previously the voting wallet status and the ticket search were stacked on top of eachother, making the page very long and awkward to navigate. This introduces tabbed navigation which allows just one to be displayed at a time.
* Ensure purchase height set for confirmed tickets.
* Show purchase height in admin screen.

- Use bootstrap to improve layout.
- Add warning banners for webserver debug mode and vspd closed.
Admin page:
- Replace listing of all tickets with form to search by ticket hash
- Fee tx status is now tracked using a dedicated field, with values none/received/broadcast/confirmed/error.
- Fee tx hex and hash are now both set in /payfee. The absense of txhash is no longer used to determine if a fee tx has been broadcast or not.
- setvotechoices can no longer be called before a fee is received.
- Remove `binding:required` from response types. It has no effect on responses, it is only needed on request types which are validated by gin.
