revert: foto de perfil e BIMI, para restaurar o servico

O site ficou a responder 502 em todos os hostnames depois do deploy destas
duas funcionalidades. A reversao vem primeiro; o diagnostico vem a seguir, com
o servico de pe.

As migracoes 0012 e 0013 ficam. Sao aditivas, nada no codigo revertido as usa,
e apaga-las deixaria a base de dados numa versao sem ficheiro correspondente,
o que parte o proprio migrate no arranque seguinte.
