Filter browser fetch network errors in Sentry

[cursor]

Changes

• Add browser-specific fetch transport errors to the Sentry client ignoreErrors list.
• Preserve the existing fetch failed filter while covering Firefox's NetworkError when attempting to fetch resource. and Chrome-style Failed to fetch messages.

Testing Criteria

• Ran yarn lint:check (passes with existing warnings).
• Ran yarn tsc --noEmit (fails on existing missing SVG module declarations in src/icons/index.ts, unrelated to this change).

Notes

• Linear: OUT-3740
• Sentry: TASKS-85

Impact & Surface Area of Change

• Client-side Sentry initialization only. The change suppresses known browser network transport failures from Sentry error ingestion and does not affect task API behavior or UI flows.
