* fix reticulum protocol loose ends from #888 review
* data: fix quoted Compose defaults blacking out every channel
* data,web: fix four defects found reviewing this PR
* web: refactor 1/7 data processing
* web: close coverage gaps in data_processing submodules
Bring every file under lib/potato_mesh/application/data_processing/ to
100% line coverage so codecov/patch passes on the 1/7 refactor PR. The
gap was a relocation of pre-existing untested branches; closing them
here keeps the subsequent refactor PRs in the series unblocked.
* Add unit tests covering canonical sender/recipient overrides,
reply_id/emoji updates on existing rows, and the rare INSERT
ConstraintException recovery path inside +insert_message+.
* Cover the non-canonical reporter and per-neighbour resolution
branches in +insert_neighbors+.
* Cover the SQLException rescue in +upsert_ingestor+, the
fallback_num branch in +touch_node_last_seen+, the limit fallback
in +read_json_body+, the unrecognised-type branch in
+store_decrypted_payload+, the +power+ telemetry_type fallback,
the default-coercion path in +resolve_numeric_metric+, and the
numeric/bare-hex paths in +canonical_node_parts+ and
+coerce_trace_node_id+.
Drop dead code surfaced while pinning behaviour:
* +clear_encrypted+ in +insert_message+ has been initialised to
+false+ and never reassigned since #633 dropped the
decrypted-text override; remove it and the four dependent
branches.
* The +rescue ArgumentError; nil+ tails in
+identity.resolve_node_num+ and +traces.coerce_trace_node_id+ are
unreachable because every +Integer(...)+ call inside is guarded by
a regex pre-check.
Add a comment to the +data_processing.rb+ shim explaining that the
+require_relative+ list is ordered by dependency rather than
alphabetically, addressing review nit #5.
