fix(icons): repair broken integration icon rendering

Two distinct bugs left integration icons broken on the /integrations page
(visible at 32-40px, hidden at the toolbar's 16px):

1. Corrupted SVG paths (Notion, Greptile, Granola, Calendly, Grafana, Bedrock):
   over-minified data dropped elliptical-arc flag digits (e.g. `A1 1 0 5.9 7`
   instead of `A1 1 0 0 0 5.9 7`); Granola's cubic stream was truncated. Browsers
   abort path parsing at the first invalid arc flag, so each rendered as a fragment
   or blank. Replaced with correct path data from canonical sources, preserving each
   icon's existing fill/gradient and bgColor.

2. Invisible glyph (Bright Data): its icon uses fill='currentColor' but bgColor was
   '#FFFFFF', and every surface forces text-white on the glyph - white-on-white.
   Changed bgColor to Bright Data's brand blue (#3d7ffc) so the white glyph reads,
   matching the white-glyph-on-brand-chip convention.
