Fixes a display problem introduced in 0.2.0: the list panel opened behind LinkedIn's own action buttons and mixed with their text, which made it hard to read and to use.

The panel is now rendered above the page and follows the button when you scroll. LinkedIn isolates its profile card (CSS "isolation: isolate" on two nested containers, plus "overflow: hidden"), which trapped the panel underneath regardless of its stacking order; rendering it outside that card is the only reliable fix.

No change to permissions, storage or data format.

The "Listes" button now attaches to both profile header layouts that LinkedIn currently serves, including the new card shown to Premium accounts. Until now, a profile served with that layout only showed a fallback banner instead of the button.

• Attachment is an ordered, closed list of two known header variants, each with its own insertion point and name lookup. A header painted after the initial render now replaces the banner with the button, without reloading the page.
• The fallback banner now says which extension it belongs to.
• The extension is named "Carnets" everywhere (manifest, overview window, banners).

No new permissions. Storage and data format are unchanged: existing lists and notes are preserved as-is.
