fix(web): settled sidebar rows use the project fallback icon

[juliusmarminge]

Settled/snoozed sidebar rows (and command-palette thread rows) rendered a generic chat-bubble icon when the project had no favicon, while every other row for the same project showed the automatically derived project icon.

Cause: those rows passed fallbackIcon={MessageSquareIcon} to ProjectFavicon, and an explicit fallbackIcon skips selectProjectIcon entirely. Removed the override in both places so all rows fall back the same way. The FolderGit2Icon override on the PR list "all projects" filter chip is intentional and untouched.

Before — settled row shows a chat bubble; sibling rows for the same project show the T3 icon:

After — a favicon-less project (fleet): the active row and both settled rows render the same derived 💻 icon:

Approvability

Verdict: Not approved

Macroscope's review found this PR not approvable — This is a small, isolated sidebar UI fix, but it changes the default icon shown for existing rows when a project has no usable favicon or saved icon. That product-default change warrants human review under the repository policy.
