## Summary
Fixes the Gmail and Google Calendar source icons by replacing
document-global generic SVG IDs (`a`, `b`, `c`, etc.) with icon-specific
IDs. This prevents inline SVG gradients, masks, and filters from
resolving against another icon instance when the icons render together
in the record table actor/source column.
## Root cause
The Gmail and Google Calendar SVG assets both used generic IDs. Browser
SVG fragment references are document-global for inline SVG, so whichever
icon appears first can hijack the other icon's `url(#...)` references.
That made the Calendar icon pick up Gmail gradients, and could also
affect Gmail depending on DOM order.

## Validation
- Rendered Gmail + Calendar in both DOM orders via a local browser
fixture.
- Verified the before fixture had 14 generic SVG IDs and the after
fixture had 0.
- Verified 4 SVGs rendered, no cross-icon URL reference problems, and no
browser console warnings/errors.
- Ran `xmllint --noout packages/twenty-ui/src/assets/icons/gmail.svg
packages/twenty-ui/src/assets/icons/google-calendar.svg`.
- Ran `rg -n
"id=\"[a-z]\"|url\(#[a-z]\)|mask=\"url\(#[a-z]\)\"|filter=\"url\(#[a-z]\)\""
packages/twenty-ui/src/assets/icons -S` and confirmed no matches.
`yarn nx build twenty-ui` could not run in this worktree because
`node_modules` is missing, and Yarn reports: `Couldn't find the
node_modules state file`.
