fix(progress-report): fold the full plan tables under the phase cards

[MendixMau]

What went wrong

A user opened the progress report on a live five-app lab project (178 plan rows, 77% built) and said: "the buildplan got merge in. But it's look like horrible HTML, and it takes tooo much room in this progress report no?"

They were right. The build section rendered the phase cards (one compact card per phase, with a bar, counts and a click-to-show row list), and below them the whole build-plan.md fragment again, fully open: every table of every phase, with the claims and drift columns, plus views A and B.

Measure	Before	After
Page size	229k characters	252k (the token panels came back too, see below)
Share of the page taken by the open plan tables	146k, 64%	folded, one summary line
Rows shown twice	all 178	none until the reader asks

The phase cards already answer "where are we" for each phase. The open tables underneath pushed the footer and the "how it is measured" notes about 140k characters further down, and the user stopped reading at the first long table.

What went well

• The phase cards themselves are good: on the same project, the 14 phases fit on one screen with bars, row counts and a "building now" tag on the active phase. Nothing about them changes.
• The page's own openTarget() script already opens a targeted <details>, so the "Jump to the plan tables" link keeps working without new JavaScript.
• The autoreload already remembers which <details> were open, so a reader who opens the tables keeps them open across the 30-second refresh.

The change

project-bin/progress-report.py: the fragment is wrapped in <details id=plan-tables class='card frag'>, closed by default, with a one-line summary ("Full plan tables and views A and B"). When there is no fragment, nothing is written (before, an empty <div> was).

Why fold and not drop

The tables still carry what the cards do not: the claims and drift per row and the script-folder and module-proof views (A and B). Those are reference material for when a count looks wrong, not the first thing to read.

Tests

• New P6 in tests/wave2/test-progress-report-polish.sh: the tables are a closed <details> with a summary, the jump link still points at them, the old open <div> is gone.
• Run locally, all green: test-progress-report-polish 36/0, test-progress-report 101/0, test-progress-report-field-fixes 101/0, test-progress-report-gitignore 15/0, test-surface-column 13/0, test-build-plan-json 70/0.
• Looked at the rendered build section on the lab project after the change: the 14 phase cards and one folded line, on one screen.

The same session found a second, larger report bug: a stale blueprint.html after a change round reopened Stage 3 and made the report show Stages 3 and 4 at 0% on a project that is 77% built. That one needs a design decision, so it is filed as an issue, not folded into this PR.
