chore: v2.7.3

[angeloINTJ]

What

The version chore for v2.7.3: SIMUT_VERSION 2.7.2 → 2.7.3, and everything that names the current release catches up with #165 (Restart without saving on /config) and #166 (the Ângulo standard, and the firmware version on the login page).

• CHANGELOG.md and CHANGELOG.pt-BR.md: a v2.7.3 section, with Upgrading and Known.
• The three READMEs, both user manuals, docs/README.md, and the landing page in its three languages.
• The product manual: chapters 1, 3, 4, 5, 9, 13, 14 and 28 plus appendix C, regenerated. Chapter 5 gains the Reiniciar section and chapter 13 the version line on the login page, with the exact strings from the language packs.
• tools/flash_budget.json: measured refreshed; budgets unchanged.

Stale since v2.7.2, fixed here

• The READMEs' "On main, not yet released" row still listed three things v2.7.2 had shipped. The row is removed, and the alpha LCD bullet that carried the same label is now named for what it does.
• tools/build_manual.py had VERSION = "v2.7.1" typed in, so the product manual's cover and <meta> said v2.7.1 through the whole v2.7.2 release. It now reads SIMUT_VERSION, as build_webui_gz.py already does.
• The pt-BR and es-ES READMEs counted 61 HTTP routes. check_authz.py counts 62, as the English README says.
• All three READMEs said 408 host test cases. CI run 36115353101 on main ran 410 (185 + 63 + 33 + 45 + 39 + 16 + 29).

Measured

All six images were built locally at this commit. The images carry the new version: the WebUI_GZ.h stamp reads ver=2.7.3.

env	used	budget margin	.bin slack under the OTA ceiling
pico_w_release	998,220	2,632	30,132
pico_w_test	1,003,764	2,632	24,588
pico_w_test_https	1,011,388	2,632	16,964
pico_w_asserts	1,000,396	2,632	27,956
pico_w_alpha	963,476	2,920	62,324
pico_w_air	1,003,328	2,960	21,460

Against the published v2.7.2 .bin: release +168 B; alpha and air are the same size to the byte.

Local gates: scan_secrets, gen_logcodes --check, check_authz, check_license, check_angulo, check_fsguard, check_air_consistency and test_h5_day_merge all pass. The product manual builds with 1,724 internal links, none broken. On the first pass the secret gate caught the new CHANGELOG quoting the very assignment it had flagged on #166; the line is reworded.

Hardware: the features were tested on the bench as #165 + #166 (see the comments on #166 and #165). This commit changes one digit of firmware and is not flashed on its own; the published .uf2 is flashed on the bench after the release.

v2.7.3 published and verified

Release assets (run 36117032546, 9 assets):

• Each .bin and .uf2 is byte-identical to a local build of main at 04b6fb2, and matches manifest.json (version 2.7.3):
  • release 1e9d9457… / 5e82b02f…
  • alpha 2a0cfcc3… / ca76a8b8…
  • air 0888bfb5… / 0e2df071…
• Both .lng packs are identical to data/lang/.
• The verifier was run first against v2.7.2 as a negative control and reported every image and both packs as differing, so a pass here is not the instrument's default.

Bench, flashed from the published simut_v2.7.3_release.uf2 (1200 bps touch + picotool, no reload confirm afterwards):

• Boot: [BMx] HW I2C addr=0x76 cid=0x58 ok=1 try=1. The USB console reports Firmware: 2.7.3.
• Login page: v2.7.3 under the name, with the Bricolage wordmark; no @SIMUT_VERSION@ left in the page. /favicon.ico is byte-identical to data/favicon.ico (731 B).
• /config carries the Restart without saving section.
• All five sensors are reading, including the BMP280 with pressure (1007.5 hPa), and the panel capture shows it.
