Replaces LICENSE (GPLv3 -> AGPLv3) and prepends
`SPDX-License-Identifier: AGPL-3.0-or-later` to every source file
across decnet/, decnet_web/, tests/, scripts/, and tools/.
Rationale: closes the GPLv3 ASP loophole so any party operating a
modified DECNET as a network service must offer their modified
source. Personal copyright (Samuel Paschuan) + inbound=outbound
contributions make a future unilateral relicense infeasible.

Touches 1565 source files (.py, .ts, .tsx, .js, .jsx, .css, .sh).
No behavior change; comments only.
A startup race between `decnet bus` being ready and the API's lifespan
hitting `get_app_bus()` at api.py:135 would set `_tried = True`
permanently, poisoning the singleton for the rest of the process: the
dashboard shows BUS OFFLINE, topology SSE falls into the bus-is-None
snapshot-only branch, mutator publish calls no-op. Only an API
restart recovered.
Replaces the one-shot veto with a time-gated retry keyed on a
`_last_failure_ts` monotonic timestamp plus a 2 s backoff. Publishers
on the hot path still pay at most one connect attempt every 2 s when
the bus is down, but the singleton auto-recovers within 5 s (one
dashboard poll) once the bus comes up.
The asyncio lock still serialises concurrent callers so the bus server
doesn't get stampeded with parallel connect attempts on startup.
