* [~] fix issue #717: validate all RFC 9000 Section 7.4.1 transport parameters for 0-RTT

RFC 9000 Section 7.4.1 requires that when a client attempts 0-RTT,
the server MUST NOT reduce 7 specific transport parameters below
the remembered values. Only max_datagram_frame_size was checked,
leaving core flow-control and stream-limit parameters unvalidated.

Add validation for all 7 MUST parameters in
xqc_conn_tls_transport_params_cb, guarded by conn_type == CLIENT
&& HAS_0RTT. Add WARN-level logging for 3 SHOULD parameters.
Persist active_connection_id_limit in session ticket storage so
the comparison uses the actual remembered value.

* [~] fix 0-RTT transport param validation: check early_data accepted, unify error codes

Address review feedback on the 0-RTT transport parameter validation:

1. Guard condition: add xqc_tls_is_early_data_accepted() check so the
   validation only fires when the server actually accepted 0-RTT.
   Previously the guard checked HAS_0RTT (attempted), which would
   incorrectly reject servers that legitimately reduced params after
   rejecting 0-RTT.

2. Error codes: unify all 8 parameter checks to use
   TRA_0RTT_TRANS_PARAMS_ERROR so xqc_conn_should_clear_0rtt_ticket()
   matches and clears the cached session ticket, preventing
   reconnection loops.

3. Fix log format specifier for max_datagram_frame_size: %ud -> %ui
   with (uint64_t) cast to match the other 7 checks.

4. Add 5 new unit tests: individual reduction tests for the 4 remaining
   MUST parameters, plus a test that verifies parameter reduction is
   allowed when 0-RTT is rejected.

* [+] add e2e case tests for RFC 9000 Section 7.4.1 0-RTT transport param validation

test 700: server reduces max_streams_bidi after first connection;
client detects the reduction on 0-RTT resumption and closes with
TRANSPORT_PARAMETER_ERROR (0x0E).

test 701: server restarts with reduced params so the session ticket
is invalid; client's 0-RTT is rejected and the param validation is
skipped, verifying the connection succeeds despite the reduction.

* [~] fix 0-RTT validation: restore max_datagram_frame_size reduction check

The RFC 9000 Section 7.4.1 validation refactor accidentally removed
the existing max_datagram_frame_size reduction check (RFC 9221).
Restore it inside the unified 0-RTT validation block and add a
corresponding unit test.

Fixes CI regressions:
- 0RTT max_datagram_frame_size is invalid
- check_clear_0rtt_ticket_flag_in_close_notify (x3)

* [~] trim redundant 0-RTT unit tests, keep 3 representative cases

Remove 10 per-parameter reduction tests that all exercise the same
if (X < Y) pattern.  Keep: all_equal (positive baseline),
all_increased (positive), initial_max_data_reduced (negative).
The 2 e2e case tests (700/701) cover real-world behavior.

* [~] replace single-param reduction test with loop covering all 8 fields

One test function iterates each MUST parameter (7 from RFC 9000
Section 7.4.1 + max_datagram_frame_size), reducing it individually
and verifying TRA_0RTT_TRANS_PARAMS_ERROR is triggered.

* [~] rename case test IDs to 701/702 to avoid collision with existing 700

ID 700 is already used by FEC frame_type_bit and crypto_error tests
on main.  Move 0-RTT param validation e2e tests to 701/702.
