KTStack 0.3.6.3

Added

• Sites: import your own certificate (full chain + private key) for a site. KTStack serves it on HTTPS and never re-mints, renews or deletes it. Re-import to update it. An alias or wildcard the certificate does not cover is refused.
• Sites: a details button in the header shows the inspector, and widens a narrow window to fit it.
• Sites and Settings: a warning when the TLD is HSTS-preloaded (.dev, .app and others). Browsers force HTTPS on these TLDs, so a site with HTTPS off won't load.

Fixed

• An open sheet such as New Site no longer disappears when you switch to another app.
