feat(schematic): add boost converter support circuitry for U2 TPS61088QRHLRQ1

Browse Source 
Add complete 5V-to-12V boost converter reference design around U2
(TPS61088QRHLRQ1) matching U1's circuit: input caps, compensation
network, soft-start cap, inductor, bootstrap cap, output caps, and
feedback voltage divider. Fix SW/BOOT pin types from power_in to
passive to resolve ERC errors. Update sym-lib-table to point to the
Q1 variant symbol library.

Constraint: Pin types must match U1's passive designation for SW/BST
Rejected: Leaving SW/BOOT as power_in | causes ERC "not driven" errors
Confidence: medium
Scope-risk: moderate
Not-tested: full ERC pass with both U1 and U2 present
