Muslim Prayer Reminder MCP

Updates persistent prayer preferences, overwriting supplied settings while preserving omitted settings. Setting fixedCity replaces stored fixedCoordinates and stores the canonical city timezone; contradictory timezones are rejected; setting fixedCoordinates replaces stored fixedCity. Can disable reminders. Fixed mode requires a supported fixedCity or fixedCoordinates with timezone; new coordinates require timezone in the same request. clearFixedLocation removes saved location and timezone and defaults to auto_travel. Combined fixed-location calculation settings are validated for the current and next local day before saving. Invalid combinations preserve the previous preferences. Auto-travel chronology is checked when a query supplies its location. Previous values are not retained for undo.
