The recipient chip-drag and paste tests render <EmailComposer>, which since
b716f95a (feat(compose): preselect identity of the active mailbox) calls
findComposeIdentityId() from @/lib/reply-identity in compose mode. Both tests
mock that module but only returned resolveReplyFrom, so vitest threw
"No 'findComposeIdentityId' export is defined on the mock" on mount,
failing all 18 tests. Add the missing export (returns null; the composer
guards with if (composeIdentityId)).
Pasting a list of addresses into To/Cc/Bcc now creates one chip per
address instead of dropping the whole blob in as a single invalid chip.
A paste is split only when it actually contains a separator; a lone
address falls through to normal editing.
- Separators: commas, semicolons, and any whitespace/newline - covers
comma/space dumps, spreadsheet columns and Outlook-style `;` lists.
- Display names are preserved: `Name <email>`, a fully-quoted
`"Name <email>"` entry, and `"Doe, John" <email>` (comma inside a
quoted name) each stay a single chip with the name intact.
- Bare-address runs split per address; a `<addr>` token is unwrapped;
tokens that aren't valid addresses are left behind in the input for
the user to fix rather than becoming junk chips.
- Deduped case-insensitively within the paste and against existing chips.
Implemented as splitPastedRecipients in email-composer-utils, layered on
the shared quote/angle-aware splitter: splitRecipients gains an optional
`separators` argument so the composer/mailto serialization boundary
(comma-only) and the paste path (`,;\n\r`) share one implementation.
Wired into the recipient chip input's onPaste handler (To/Cc/Bcc).
