[FEATURE]: Disable as many rewrite rules as we can, like attachment endpoints etc.

[jakewrfoster]

Description

Alleyvate should disable as many rewrite rules as possible, like attachment endpoints, etc.

Use Case

Many rewrite rules are not in use on the sites that we build and add more complications than they solve. These unused rewrite rules should be removed by default so that they:

• cannot be abused
• no longer "reserve" endpoints
• no longer serve content that may not be styled or expected to be indexed or otherwise publicly visible
