feat: roles array, getDirettivo, setRole into addRole, changes... (#16)

* feat: support multiple roles in tg.permission table

* feat: add getDirettivo route

* build: generate db migration

* fix(getRole): if no role, returns `["user"]` instead of `user`

* fix(getDirettivo): better output shape

* fix: varchar is bullshit, switching to text

TODO: maybe merge the two DB migrations into one

* fix: add back logic commented out

* feat: not role is now null instead of 'user'

* refactor: query optimization, removing DUPLICATE_ROLE error

* feat: removeRole procedure

* release: v0.11.0
