For the crust: Preheat the oven to 350 degrees F. Lightly spray an 11-by-7-inch tart pan with a removable bottom with nonstick cooking spray.
Add the butter and habanero to a small saucepan and place it over medium heat. Cook, swirling the pan occasionally, to melt the butter, then turn off the heat and let cool to room temperature.
Pulse together the flour, walnuts, brown sugar and salt in a food processor. With the processor running, drizzle in the butter until the mixture comes together. Press the mixture into the prepared tart pan. Bake until the crust is lightly golden and feels firm to the touch, 10 to 12 minutes. Let cool completely before filling.
For the filling: Place the chocolate in a heatproof bowl and set aside. Add the cream and bourbon to a small saucepan and heat to simmer. Pour the hot cream mixture over the top of the chocolate and let stand 3 to 5 minutes, then stir until all the chocolate is melted and the mixture is smooth. Stir in the vanilla until incorporated. Pour the ganache into the tart shell. Let cool at room temperature until set, about 4 hours, or chill in the refrigerator for at least 2 hours.
For the decoration: Line a sheet tray with a silicone mat. Melt the white candy melts along with 3 tablespoons coconut oil over a double boiler or in the microwave at 30-second intervals. Do the same with the orange candy melts and the remaining 2 tablespoons coconut oil in a separate bowl. Pour the white chocolate in an even layer onto the silicone mat, then use an offset spatula to spread into a thin even layer. Drizzle the orange chocolate over the top of the white. Using a skewer or toothpick, swirl the orange into the white chocolate. Sprinkle with additional chopped walnuts, red dragrees and gold edible glitter. Let cool until set, about 1 hour at room temperature or 12 to 15 minutes in the refrigerator. Remove the mat from the sheet tray and break the candy into shards. Top the tart with sweetened whipped cream and candy shards before serving.
