dev-stack: lower NOSTR_TRANSPORT_MAX_EVENT_CONTENT_LENGTH to 20000

Sharding only fires when an outbound RPC response exceeds the per-
event content cap. With the production default (40_000) it takes
hundreds of seeded payments to make `list_payments` trip sharding —
the test_transport_suite.py test #2 was reproducibly hitting ~39K
just shy of the threshold even with 90 round-trips and 600-char
memos.

Lowered to 20_000 in the dev compose so the same test trips
sharding with ~60 fat-memo payments (~20s of seed time). Production
deployments leave this unset and inherit the 40_000 default.

The lower threshold doesn't mask any real behavior — the shard
envelope is identical at either threshold, and the unit tests in
LNbits exercise the boundary cases independently
(tests/unit/test_nostr_transport.py::test_split_content*).
