chore(s0): remove unused LinePostSkill entity and DTOs

AdoS0MfgLinePostSkill (table LinePostSkill) had no Controller or
repository injection; the active line-post-skill flow uses
AdoS0LineSkillDetail instead. Drop the entity, the two unused
upsert DTOs (AdoS0MfgLinePostSkillUpsertDto, AdoS0MfgLinePostUpsertDto),
and the Startup CodeFirst registration. Physical table left in place
for separate data-cleanup pass.
