docs: accept ADR 0048, one generic image with installed modules outside it
Ekklesia produces one platform image with zero feature modules. Installed
modules live in installation-owned storage selected by EKKLESIA_MODULES_DIR
(/var/lib/ekklesia/modules in the image, <repo>/modules in development),
mounted read-only and discovered only at a controlled restart. An installed
module directory is self-contained; the platform lends it no dependencies.

Uninstall is distinct from disable and purge: removing module code keeps its
data and stored state, and applied migration history of an absent module is
retained and reported instead of blocking planning. Present modules and Core
stay strictly validated.

Supersedes in part ADR 0044 (composition from pinned sources) and ADR 0009
(rejection of history absent from the inventory); amends ADR 0006; extends
ADR 0028 and ADR 0030. ADR 0047 gains a cross-reference saying it must be
revised before acceptance, and deploy/README.md notes that its composition
model is being replaced. No code, Dockerfile, Compose, CI, or test changes.

# Architecture decision records
ADRs capture durable choices that affect more than one package or phase.
- Filenames use a four-digit sequence followed by a short kebab-case title.
- Status is `Proposed`, `Accepted`, `Superseded`, or `Rejected`.
- Accepted ADRs are immutable except for status and cross-reference corrections.
- A changed decision receives a new ADR that links to and supersedes the old one.
