[Pipe] Support receiver-side async takeover for TsFile conversion

[Caideyipi]

What does this PR do?

Adds resilient receiver-side handling for Pipe TsFile type-conversion failures.

• Adds connector.exception.data.convert-on-type-mismatch.tsfile.async-load (and the sink.* alias), defaulting to true, and propagates the setting with a stable conversion task ID.
• Deduplicates seal and retry requests by deterministic task ID. Retries reuse the existing task status and context instead of starting duplicate conversions.
• On a type-mismatch conversion failure, atomically hands the TsFile and mod file to the receiver active-load async directory and marks the task receiver-owned.
• Treats temporary unavailability and OOM as a pause of local conversion only; input files and parser progress remain retryable.
• Reuses Pipe parser state and checkpoints across retries, including iterators, pending tablets, page and chunk metadata, file index, and pending statements.
• When async takeover is disabled, sender retries return the current task status and never create a second conversion task.

Tests

• Added or updated parser, receiver, transfer-request, active-load path and scanner, load utility, and conversion-task-manager unit tests; 85 targeted tests passed.
• DataNode compilation passed.
• Spotless and git diff --check passed.
