**What
Four production sites were ignoring json.Unmarshal return values:

• channels.go List + Webhook: corrupt JSON rows would produce empty config / allowed_users without any signal.
• manager.go FetchWorkspaceChannelContext: empty config would fall through to DecryptSensitiveFields failure, masking the root cause.
• messagestore extractFilesFromResponse: _ = json.Unmarshal discarded parse errors on the probe wrapper.

Fix
All four now log the error at the point of failure so operators can spot data-corruption or schema-drift incidents. No behavioral change — the previous code continued with zero values, and the new code still continues after logging.

Test plan

• CI / Platform (Go) passes (no new compile errors, log is already imported)
• lint-required-context-exists-in-bp passes
• No new tests needed — this is a pure observability fix with no new branches.

fix(channels,messagestore): log json.Unmarshal errors instead of silently dropping them ... e179485a0e

Four production sites were ignoring json.Unmarshal return values:

- channels.go List+Webhook: corrupt JSON rows would produce empty config/allowed_users without any signal.

- manager.go FetchWorkspaceChannelContext: empty config would fall through to DecryptSensitiveFields failure, masking the root cause.

- messagestore extractFilesFromResponse: _ = json.Unmarshal discarded parse errors on the probe wrapper.

All four now log the error at the point of failure so operators can spot data-corruption or schema-drift incidents.

The stated scope is observability/no behavior change, but the diff changes behavior on unmarshal failures. channels.go List/Webhook now continue on corrupt config or allowed_users where the previous code continued with zero values, and manager.go now returns early before DecryptSensitiveFields. Please either preserve the previous flow after logging, or make the intentional skip/return behavior explicit and add focused tests for the new semantics.

fix(channels,messagestore): preserve previous flow after logging json.Unmarshal errors ... 212842bc3f

Addresses review feedback on PR #1899: the stated scope is observability/
no behavior change, but the initial diff changed control flow on unmarshal
failures (continue/return instead of proceeding with zero values).

This revision keeps the error logging but restores the previous flow so
that List/Webhook proceed with nil config/allowedUsers and
FetchWorkspaceChannelContext proceeds to DecryptSensitiveFields, exactly
as the bare `_ = json.Unmarshal` did before.

PM 2nd-approve per direct CTO request. Replaces silently-dropped json.Unmarshal errors with structured log lines in channels and messagestore paths. Behavior preserved (fail-soft fallback), observability improved. CR2 prior R_C on observability concern already resolved by author per CR2 re-approval.
