Container log live-stream review fixes (frontend only):
- F1/F2: demux Docker's multiplexed (non-TTY) stream at the BYTE level by
frame length, decoding only payloads. Previously the stream was text-decoded
whole and cut on '\n' before stripping 8-byte headers, which desynced when a
length low-byte was 0x0a or a header byte was >= 0x80. streamContainerLogs
now hands the processor raw Uint8Array chunks; createLogStreamProcessor is
rewritten to parse frames, concatenate payloads, split lines on 0x0a, and
UTF-8-decode complete lines. formatLogs is called without stripHeaders so
headers are not stripped twice. Added explicit byte-frame tests.
- F3: request timestamps=1 internally and resume reconnects from the parsed
RFC3339 timestamp of the last line (not client wall-clock); strip the prefix
before display when the user's timestamps toggle is off; dedup the inclusive
`since` boundary lines on reconnect.
- F4: run the fetch stream URL through dockerMaxAPIVersionInterceptor so it
matches the axios getContainerLogs version pinning.
- F5: notify on stream error once per reconnect loop, not every 3s retry.
- F6: resuming Live no longer wipes the buffer (startStream(false)) and
continues from `since`.
- F7: service/task logs still poll; documented the re-render limitation
(out of scope: issue #2 is container logs).
- F8: flush the trailing partial line on the error path too (parity with onEnd).

Replace the 3s $interval polling of container logs with a live HTTP
stream, and stop re-writing already-rendered lines (fixes selection bug).
- streamContainerLogs (containers.service.ts): fetch + ReadableStream
reader with follow=1, same-origin credentials:'include' (httpOnly JWT
cookie; CSRF only guards mutations), agent-target / manager-operation
headers replicated for Agent/Edge, AbortSignal-driven lifetime.
- containerLogsController: stream instead of poll; append parsed lines
into the buffer (push, never replace), cap at 5000 lines trimming from
the head; AbortController on pause/destroy/param-change; reconnect with
3s backoff resuming from `since` (dropping tail) on stream end/error;
Live toggle pauses/resumes the stream; tail/since/timestamps changes
restart the stream.
- log-viewer: `track by log.id` (was $index), filtering moved out of the
template into the controller (applyFilter via $watchCollection), removed
inert force-glue, decoupled auto-scroll from log collection, relabelled
"Auto-refresh logs" -> "Live logs", clearer empty states.
Backend unchanged (logs already stream transparently through the Docker
proxy). Shared task/service log views keep working via the new id'd lines.
