usage_report: split _usage_report_render.py 310 -> 181 + 123 + 24
Verified by the 100%-coverage tests from the previous commit, written
before this seam existed.

_cpu_table/_dedupe_ram/_ram_table/_gpu_table move to
_usage_report_tables.py with the two constants they own. _md_escape and
_fmt_h move to _usage_report_format.py: both the tables module and the
render module need them, so a third module is what avoids a cycle.
Import sites name the owning module; no re-export barrel.

usage_report.py needed no edit - it imports _fmt_h and _render_report
from the render module, and both names still resolve there.

Evidence the move was verbatim: an AST comparison of all 10 functions
against HEAD reports 10 identical, 0 mismatches. That matters because I
retyped rather than cut-and-pasted, and did briefly introduce a literal
× where the original had × - ruff's RUF001 caught it.

Coverage stays 100% line+branch on all three (15/55/54 stmts, 4/10/14
branches, 0 missed). Test count 43 before and after, summed across the
five files it now lives in - the check that matters for a test split,
since a file outside the runner's glob is silently never collected.
Directory total 143 passed, unchanged.

Ran the real program: a full report from today's atop + pmon logs, every
section rendering through the new boundaries including the RAM sibling
dedupe and its (+20 more) truncation.

Over-cap 41 -> 39. No suppressions; a shared test-helper module was tried
and abandoned because name-tests-test would have needed an exclusion.
