Fixes #479

Problem

The Meta messaging adapters parse created_time and updated_time with time.RFC3339. Graph returns these values with an offset without a colon (2022-07-12T19:11:07+0000, see the example response in Meta's Conversations API docs), so parsing fails, the error is ignored and the zero time is stored. On our self-hosted v7.31.1 instance all 265 collected Instagram messages had remote_created_at 0001-01-01T00:00:00Z, conversations showed the year 1 and no reply window was recorded.

Change

• messaging_meta.go: conversation updated_time and message created_time (used for the reply window) go through nativePostTime, which already accepts RFC 3339 and 2006-01-02T15:04:05-0700.
• messaging_meta_history.go: metaMessageView.provider does the same.
• messaging_meta_test.go: conversations with Graph-style timestamps (message order, last message time, reply window = latest inbound + 24 h) and history.
• CHANGELOG.md: entry under Unreleased, Fixed.

Verification

• go vet ./internal/platform/ and gofmt -l clean.
• go test ./internal/platform/ ./internal/services/messaging/ pass (Go 1.26.10).
• Without the fix both new tests fail; with it they pass.

Summary by CodeRabbit

• Bug Fixes
  • Facebook and Instagram direct-message timestamps with numeric timezone offsets are now retained correctly. Message ordering, conversation activity times, and reply-window tracking reflect the actual timestamps, including when a conversation has no messages.
• New Features
  • Self-hosted administrators can record Telegram bot publishing certification evidence.

Explanation

Issue #479 requires colonless Graph timestamps to parse in conversation updated_time, message created_time, and history. The diff routes all three paths through nativePostTime. The test summary covers message ordering, timestamps, reply-window expiry, no-message conversation updated_time, and history timestamps. The changelog records the fix.

Full details: Docstring Coverage

Explanation

Docstring coverage is 33.33% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 3 functions across 3 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.

Add coverage for conversations with no messages.

The current test only covers conversations where the latest message replaces updatedAt. A regression to RFC3339-only parsing can leave a new conversation's LastMessageAt at the zero time when Meta returns no messages. Add a separate adapter test for this branch.
