                                            [FIX] viin_brand_mail: fix chatter contrast in light and dark schemes

DARK: the mail chatter embedded in the Odoo 19 spreadsheet editor's
comments side panel was unreadable. Odoo keeps the spreadsheet a light
island inside a dark app (its dark-bundle-only
o_spreadsheet_extended.dark.scss forces .bg-white back to white and
pins .btn to a dark label), but core repaints only the button label,
not the fill, leaving half of every pair in the wrong colour scheme.
Finish that light island for the embedded chatter instead of darkening
it, scoped entirely under .o-spreadsheet. Measured live at 1440px in
dark mode, before -> after: Log note 1.19 -> 7.92, Activity
1.19 -> 7.92, Send message 2.17 -> 8.24, author name 2.63 -> 10.31,
timestamp 2.59 -> 6.11, message body -> 9.25.

The same two message nodes the island fix above touches - the
empty-message placeholder (3.37:1 worst) and the (edited) marker
(4.04:1 worst) - were unreadable everywhere OUTSIDE that island too,
because core dims both a second time on top of a tier already tuned to
clear AA once. Fix them product-wide instead of leaving the island as
the one readable spot: every form-view chatter, the Discuss thread
canvas and every chat window, on the panel and on all three
message-bubble tints. With that rule in place the island's own
placeholder correction became a pure duplicate of it and was dropped.
The island's (edited) rule is kept and hardened with its own colour,
because the product-wide fix lands that marker on the dark metadata
tier, which measures 2.34-2.59:1 on the island's light bubbles - too
dark for that ground.

LIGHT: the mail message muted tier renders below AA wherever it lands
- 4.06:1 on a message bubble, 4.20:1 on the chatter panel - and two
nodes are dimmed further by opacity utilities to 2.7:1 and 2.4:1. The
shared $text-muted token is deliberately left untouched: it also paints
off/disabled affordances that WCAG exempts, and repointing it would
change roughly 380 nodes across 205 templates. Re-point the tier for
mail message surfaces only. After: 5.48-6.11 across the panel and all
bubble variants. Dark stays provably unaffected, since the light rules
compile to zero bytes in the dark bundle.

Also drop a rule that went dead once the comments panel lost its
background utility - it was this module's only reference to another
repo's class.

A comment on the read-conversation muted tier said its
--secondary-color token "does not flip" in dark - true only while
$o-main-color-muted and $body-secondary-color were two independent
Sass values. dark_palette.scss has since aliased the former onto the
latter, so both names now resolve to the one tier this rule already
reads: the rule was right, the explanation had gone stale. Reworded to
name the tier through its own alias chain instead of restating a
divergence that no longer exists.

Guard every case above with tests that assert computed WCAG ratios,
never colour values.
