Server export now includes encryption key, themes, and all config files.
Client export bundles all DashCaddy localStorage keys (19 named + dynamic
widget keys) as browserState. Restore handles both server and browser
state in one operation. Legacy v1.0 import format still supported.
Removed redundant Export/Import toolbar buttons — Backup modal is now
the single entry point.
