fix: bulk import should not inject hardcoded timeout defaults

When a backend block in haproxy.cfg does not specify explicit timeout
values, the bulk import was injecting hardcoded defaults (connect 10s,
server 60s, queue 60s) into the database. These then appeared in the
generated config and overrode the agent's defaults section. Now, only
explicitly declared timeouts are stored; omitted ones remain NULL so
the agent's existing defaults section stays in effect.
