Matthieu MALVACHE 7e42d2dedf fix(calendar): produce correct JMAP patch when removing recurrence rules
When editing a recurring event and clearing its recurrence, the update
patch was omitting recurrenceRules entirely instead of setting it to null.
The server never received the change. Also clear recurrenceOverrides and
excludedRecurrenceRules so orphaned exceptions don't persist. Same fix
applied to locations and alerts removal.

Fix "this_and_future" scope overriding recurrence removal by reordering
the spread so user updates take precedence over master's original rules.

Configuration

Create a .env.local file:

APP_NAME=Your Webmail
JMAP_SERVER_URL=https://your-jmap-server.com

Runtime vs Build-time Configuration

Variable Type Description

JMAP_SERVER_URL Runtime JMAP server URL (required)
NEXT_PUBLIC_APP_NAME Build-time Legacy fallback for app name

Runtime variables are read at request time, enabling post-build configuration (ideal for Docker).

Build-time variables are baked into the bundle and require a rebuild to change.
