Remove path from fields in Accounts struct

[mcintyre94]

This PR updates the fields of an account struct from eg:

pub post: Box<Account<'info, dot::program::Post>>,

To eg:

pub post: Box<Account<'info, Post>>,

This works correctly because lib.rs includes use dot::program::*;, so either form is equivalent.

This is a workaround for an issue parsing seeds in Anchor: coral-xyz/anchor#2268

In short, Anchor reads the imported Post struct as just being called Post, but reads the account as dot::program::Post, which doesn't match and errors. By just generating it as Post in Seahorse we avoid this issue.

Full details in the Anchor PR description + Seahorse Discord: https://discord.com/channels/1005658120548270224/1005658120988655647/1043989626114814012

Mentioned in Discord, but would it be feasible to also use each account struct? Just to prevent the problem where somebody makes an account in a separate module and tries to use it in an instruction but can't.

Closing this for now, opened issue #60. Also opened #59 as a prerequisite. Since that's definitely a lot bigger than this PR I don't think it's worth keeping this one open for now.
