fix(imap): oauth2 url fix for outlook (#1701)

## What?

- Added try-catch block to make it easier to debug OAuth2 errors
encountered while authenticating IMAP.
- Revised Outlook URL generation code for updated Entra ID redirect

## Why?

I wasn't able to authenticate my Outlook emails previously. I'm not
fully sure if the documentation clearly states that you need your Entra
ID redirect to be configured as "Web" rather than "Mobile & Desktop
App," but that is also a needed fix.

chore: sync gomod2nix.toml (#1672)

## What?

Regenerates `gomod2nix.toml` to reflect the current `go.mod` / `go.sum`.

## Why?

Keeps the Nix build in sync with Go module changes. Without this, `nix
build` fails when new or upgraded Go deps are missing from
`gomod2nix.toml`. Generated automatically by the gomod2nix sync
workflow.

fix: gmail 555 error when sending (#1496)

## What?

Fixed the SMTP "555 5.5.2 Syntax error" that occurred when sending
emails with CatchAll
enabled by formatting the bare email

## Why?

When CatchAll is enabled, the `From` field displays a formatted address
like
"`Name email@example.com`". This formatted value was being passed
directly to Gmail's SMTP
MAIL FROM  command, which expects only the bare email address.

According to RFC 5321 (SMTP protocol), the MAIL FROM command must
contain only the
mailbox (email address), not a formatted display name. The display name
belongs in the
message headers (the From: header), which is separate from the SMTP
envelope.

fix: add cap to image rendering (#1621)

## What?

Adds a cap to image rendering, so that the images dont break the whole
TUI

Previously, big images would make the whole screen black, when scrolled.

fix(tui): update folder unread counter (#1493)

## What?

After deleting or archiving emails, the per-folder unread counter shown
in the sidebar (`(N)`) now updates immediately. The four handlers
(`DeleteEmailMsg`, `ArchiveEmailMsg`, `BatchDeleteEmailsMsg`,
`BatchArchiveEmailsMsg`) decrement `m.unread[folder]` for each removed
unread email via a new `decrementFolderUnreadForRemoved` helper that
mirrors the existing read/unread path (`DecrementUnreadCount` +
persist); undo re-increments it. Adds five tests.

## Why?

The delete/archive handlers mutated the email stores but never touched
`m.unread`, so the sidebar folder counter stayed stale until the next
server fetch (#1404). (`syncUnreadBadge` only sets the macOS dock badge,
so it did not address this.)

Closes #1404
