Setting a password, banner or TLS material AFTER deployment forces a
container recreate on every change. The deploy wizard now lets the
operator set service config up-front so the initial build has the
right env from the start.
Mechanics:
- Extracted the schema-driven field rendering out of ServiceConfigForm
into a standalone ServiceConfigFields component (no API/buttons,
just inputs + onChange). ServiceConfigForm now delegates to it.
- Wizard step 2 (CONFIGURATION) renders one accordion block per
selected service; clicking a service reveals its schema-driven
inputs and a 'N set' badge tracks how many overrides are populated.
Removing a service (back to step 1) drops its config so the INI
doesn't carry orphans.
- _buildIni emits one [<prefix>.<svc>] group subsection per service
with at least one override. The INI loader's prefix-matcher
applies it to every ${prefix}-NN decky in the batch, so one block
covers all clones.
- Multi-line string values (PEM textareas etc.) are escaped as \n
on the way into INI; downstream consumers re-expand.
