Street Level: docs for the OPEN exception, panel freshness and what stops a request

- SECURITY.md: OPEN also takes the link's point when the screen centre
  cannot be picked at all.
- TOOLS.md: the panel's own link opens Street View only for a result issued

- Changelog: the hiding modes stop a request, collapsing the panel does not;
  failure cards are in the interface language.
- CURRENT-STATE: a posted view without a point grounds its look-at too.
