Collapses the triplicated Endpoint field lists in discovery.py (the with_* methods, Inventory.describe/present, and Discovery._described/_presented all re-spelled the same keywords), inlines a few trivial one-line wrappers, and removes the duplicated assignments between __init__ and async_redescribed in entity.py.

No behavioural change; the existing discovery and entity test suites are the gate. describe/present now take **fields typed with a TypedDict/Unpack pair so mypy can still check the dataclasses.replace() call.

Tested with tools/check (lint, format, mypy, full pytest run).

Checked this against refactor/code-hygiene in a worktree. tools/check is green (lint, format, mypy strict, full pytest run, 1218 passed).

Traced the two things most likely to hide a behavioural change in a "pure refactor" like this:

CampervanNodeEntity.__init__ now calls async_redescribed(node), whose early-return became if node == getattr(self, "node", None): return. On first construction self.node doesn't exist yet, getattr returns None, the dataclass __eq__ safely returns False against None (no AttributeError, no exception), so init falls through and sets node/device_info exactly as before. The if self.hass is not None: self.async_write_ha_state() guard beneath it (unchanged) is also False at construction time, since Entity.hass defaults to None before add_to_hass. So no spurious async_write_ha_state() call on construction, and later calls from platforms.py's follow_the_inventory() still skip the rebuild when the node hasn't actually changed, same as pre-refactor. This all matches how platforms.py drives it (construct once per node, cache in held, then carried.async_redescribed(node) on every subsequent announce).
@callback in this codebase (homeassistant.core.callback) just sets a _hass_callback marker attribute and returns the function unchanged — it isn't enforced anywhere coordinator.py's subscribe/notify touches. Calling async_redescribed synchronously from __init__ is no different from platforms.py already calling it synchronously post-construction, so no issue there either.

Also checked the TypedDict/Unpack field names in _DescriptorFields/_MetaFields against every keyword Discovery._described/_presented pass into describe()/present() — they match exactly, and it's the minimal fix for the mypy-strict replace(**dict) problem (two small TypedDicts, used only where needed, nothing speculative).

No behavioural drift found, no dead code left behind (with_descriptor/with_meta/with_label/_forget_label_pieces/query_frame/_bus_changed/_notify are all gone with no remaining references), and the moved comment in Inventory.describe keeps the one load-bearing sentence from the deleted _forget_label_pieces docstring. Nothing to change.
