fix(protocols): makers name the rejected argument and value in error messages - #2405

Follow-up to #2405, which left these out of #2296's checklist. #2406.

- hopopt.py / ipv6_opts.py: _make_opt_pad's Pad1-length warning, matching
  MH._make_opt_pad's text from #2405 (alias swapped).
- httpv2.py: HTTP.make's unsupported-frame-type guard.
- pcapng.py: PCAPNG.make's unsupported-block-type guard (the dispatcher,
  not _make_block_dsb, which #2405 already fixed).

Added the missing Raises: docstring section on the two make() guards,
matching #2405's MH.make/_make_block_dsb docstrings.

Test: tests/protocols/test_maker_invalid_format_messages_2406_unit.py
(new, 9 tests/18 subtests), plus a ReadersKeepInvalidFormat pin that
_read_opt_pad on both protocols still says "invalid format" -- the exact
twin of the maker guard changed here. Confirmed fail-without-fix: 12
failures against unpatched pcapkit, each a message-text mismatch.
tests/protocols/ in full: 2020 passed/51388 subtests/0 failed. mypy and
pylint findings on the 4 touched files are unchanged from main.

…egistry and registration prose (#1103)

#1103 whole-repo prose sweep over the maker-message wave (#2296, #2404, #2405,
#2407) and the __proto_dest__ registry refactor (#2392, #2403).

Docstrings corrected where the prose did not match the code:

* ``Protocol`` -> ``ProtocolBase`` in the ``register``/``register_protocol``
  cross-references (protocol.py, internet.py, link.py, transport.py, sctp.py,
  registry/protocols.py).
* ``Raises:`` entries for the ``bool`` port guard (#2287) in TCP, UDP and SCTP
  ``make``, and for HTTP/1's request-without-``uri`` guard.
* ``protochain`` documented on both sides of its narrowing to ``None``
  (protocol.py, misc/null.py, #2317), and ``__init__`` names the
  ``__own_make_keywords__`` exception to its keyword check.
* IP reassembly names the IPv6 ``M`` bit and which buffer an atomic fragment is
  isolated from (#2270); ``_check_code`` names ``register_protocol_code`` among
  its callers (#2186).
* HIP's shared lifetime helper says where the octet appears instead of counting
  the makers that carry it, and ``_make_opt_pad`` warns and makes a ``PadN``
  rather than raising as its reader does.

Before/after narration replaced with present tense, the pattern #1103's round 6
banned: the ``__proto_dest__`` prose in the registration and vendor tests, and
the #2296 maker-message module docstring.

AST guard (``ast.dump`` via util/vendor_code_changed.py's ``code_of``, with
docstrings and bare string literals stripped) confirms all 16 touched files are
prose-only against e48062c. 135 tests and 334 subtests pass across the four
touched test modules, tests/test_docstring_contract.py, and the convention and
issue/PR-role guards in tests/project/.

Problem: of the 60 pull requests merged in the #2312-#2407 range, only
#2334, #2336, #2337, #2340 and #2348 wrote a 1.5.0 changelog entry, and
#2398 and #2403 only reworded lines that were already there. Every other
user-visible change in the range -- wire-semantics fixes, maker guards,
reassembly behaviour, public-API and error-message changes -- went
unrecorded, so the entry no longer describes the release.

Fix: one entry per user-visible pull request, in each module section's
existing style and ordered by the issue it closes. Two pairs share a
bullet, since each is the direct follow-up of the other: #2393 with
#2401, and #2405 with #2407. The diff on the entry file is purely
additive.

Internal-only work is left out deliberately: dependency and action bumps
(#2387 to #2391), test-only and docs-prose passes (#2333, #2376, #2379,
#2380, #2402), the unreachable-branch removal (#2378), and the #: comment
marker the HIP Group and Packet crawlers now write (#2381). That last one
renders nothing either way: the marker lands inside the generated
_missing_ body, conf.py's exclude-members drops _missing_ from autodoc,
and a comment in a method body is not an attribute comment to begin with.

#2392 and #2403 are recorded together, under Added rather than Fixed, for
the declarations they introduce: __proto_key__ on the seven classes owning
a __proto__ registry (#2392), __proto_dest__ on the four enum registries
and Vendor.PROTO_DEST to generate it (#2403). Both PRs added the autodoc
entries, so both are rendered public attributes. #2392's rejection-message
change is deliberately not recorded as a fix: the bare "code must be ..."
text it prefixed came from _check_code, which #2193 introduced and which
is in no release tag -- absent at v1.5.0b14 -- so no released version ever
emitted it. #2403 is no longer skipped as internal because it reworded an
existing bullet to name __proto_dest__ while nothing credited the
attribute's introduction.

Four claims are corrected against the source rather than carried over:
FTP_DATA shipped in pcapkit/protocols/application/ftp.py from 1.0.0, not
1.4.0 (class FTP_DATA(Raw) is there at v1.0.0); #2365's pre-fix fallback
read cmmd.value, so a .value-carrying object was accepted unchecked
rather than raising; #2399 left the dpkt adapter and the adapters'
ModuleNotFound raises alone, so it claims no universal prefix; and
#2397's old tail did name the version it got, so the entry quotes it and
gains the :issue:`2302` it was missing. #2370's "a Section Header Block
... still fails" sentence is dropped: #2369 settles the byte order first,
and an SHB built from raw octets with ctx=None now rebuilds byte-exact in
both byte orders.
