wgdashboard issue with sqlite table names, does not handle interface names with dash in name

[epiecs]

Describe The Problem
Wireguard allows interfaces names that match the following regex: ^[a-zA-Z0-9_=+.-]{1,15}$

In dashboard.py the on line 490 the create_table function crashes when using an interface name such as wg-test.

The reason for this is that SQlite does not allow dashes in database names unless they are quoted. As reference see this {stackoverflow answer](https://stackoverflow.com/a/3694291).

The fix is to replace CREATE TABLE IF NOT EXISTS {i} ( with CREATE TABLE IF NOT EXISTS \"{i}\" (

This will fix the login error. However there are some more locations in the code that still need escaping. For example opening an interface wont work.
