Reduce TLS memory requirements for KOReader sync

Split heap gate into separate free-memory (50KB) and largest-block (20KB) thresholds based on field measurements. Enable wolfSSL single-precision ECC to use fixed 256-bit arrays instead of heap-allocated fast-math bignums, reducing TLS handshake memory footprint. Reclaim ~7KB by right-sizing ESP timer task stacks and move WiFi code out of IRAM to free ~25-30KB for heap. Add memory audit landmarks for font and EPUB allocations.

 // Streaming deflate decompressor wrapping uzlib.
 //
+// NOTE: retained ONLY for FontDecompressor's tiny one-shot flash-resident group
+// decompressions, where uzlib's ~1KB state beats tinfl's ~11KB on the
+// OOM-sensitive render path. All throughput paths (zip entries, PNG IDAT) use
+// InflateStream (lib/miniz), which decodes several times faster.
+//
 // Two modes:
 //   init(false)  — one-shot: input is a contiguous buffer, call read() once.
 //   init(true)   — streaming: allocates a 32KB ring buffer for back-references
